- WHAT IS STAR 2000?
- Star 2000 is a freeware subset of Star Base - a
- commercial program distributed by Debonair Soft-
- ware (for our address - see Page 5-6).
- While being a copyrighted program, Star 2000 can
- be freely distrubuted as long as all the files,
- including the documentation, stay together.
- This is not just a demo: Star 2000 is a fully
- functional program, just scaled down as compared
- to the original. The limitations and differences
- are listed on Page 4-2 of this help.
- While some users of Star 2000 will have a need
- for Star Base, many should be perfectly happy with
- the free version. We hope you enjoy the program.
- DATABASE WINDOWS
- The database windows display the data on stars,
- deep sky objects (DSO) and on the objects of the
- Solar System (Sun, Moon and the planets).
- They are opened, respectively, by clicking on
- <List|List stars>, <List|List deep sky objects>
- and <List|List Solar System>.
- If a window is already open, it will be just
- brought it to the top. If, however, the parameters
- describing window contents have beeen changed, the
- window will be updated to reflect the change (this
- is also true about the map and HR plot windows).
- The current top window can be closed by pressing
- the Escape key.
- 1-3
- DATABASE OPERATIONS - I
- To move around a data window use the scroll bars
- on the right, or the keyboard:
- * Clr/Home - go to the top of database,
- * ⇧ or ⇩ - page up or down, respectively,
- * ⇦ or ⇨ - line up or down, respectively.
- The other operations are enabled only in the DSO
- and star (not in Solar System) window:
- * Clicking on a data line will display the object
- in the Full Data dialog.
- * Double-clicking will tag an object (marking it
- with a ">") or untag it again. The listing can
- be then limited to tagged objects only. The
- <List> menu has also "Untag all" options.
- 1-4
- DATABASE OPERATIONS - II
- * The last tagged or accessed star is displayed
- in inverse video (see "Finding an Object").
- * The coordinate system used in data windows can
- be changed by clicking on <List|Set list frame>
- * Selecting <List|Mapped only> will limit the
- listing to objects drawn within the most recent
- map - the change is effective immediately.
- * The listing order can be changed by clicking
- on <List|Sort ...> menu entries. Objects can be
- sorted by two attributes, in increasing or de-
- creasing order.
-
-
- 1-5
- DATABASE SUBSET SELECTION
- The <List|Select...> menu entries enable data-
- base filters: only objects with attributes falling
- within specified ranges will be listed.
- A dialog will show up, asking for low and high
- limits ofeach attribute. An empty field means no
- filtering of that attribute from that side (top or
- bottom). If both fields of an attribute are left
- empty, the attribute will not be filtered at all.
- You may also limit the selection to previously
- tagged objects.
- For stars, the spectral type limits may contain
- just a single letter and a digit, e.g. F9.
-
- 1-6
- OBJECT CO-ORDINATES
- All objects can be displayed or mapped using one
- of the following co-ordinate systems:
- * Equatorial: declination (α) and right ascension
- (δ) (the latter in angle or time units)
- * Ecliptic: latitude (β) and longitude (ג)
- * Galactic: latitude (b) and longitude (l)
- * Horizon: azimuth (A) and elevation (H).
- The horizon system uses parameters entered pre-
- viously via <Options|Set horizon frame>.
- The mode of right ascension display can be chan-
- ged by clicking on <Options|Show RA as "hhmm">.
- The system used in all textual output is chosen
- from <List|Set list frame>.
- 2-1
- STAR DATA
- In addition to co-ordinates, the following data
- is displayed in the star database window:
- * Catalog number: YBS 0001 to YBS 9100, with a
- "D" denoting multiple stars;
- * Greek/Numeric and constellation name, as EpsUma
- * Apparent (m) and absolute (M) magnitudes in the
- visual wavelength range;
- * The B-V color index;
- * Distance (d) in light years;
- * Harvard/Yerkes spectral/luminosity class, shown
- abbreviated (the full version can be seen in
- the Full Star Data dialog).
-
- 2-2
- DEEP SKY OBJECT DATA
- In addition to co-ordinates, the following data
- is displayed in the DSO database window:
- * The NGC catalog number;
- * Object type (abbreviated to three letters):
- Gxy - galaxy
- Neb - nebula
- PlN - planetary nebula
- OCl - open cluster
- GCl - globular cluster
- NCl - cluster with nebular associacion
- * Visual magnitude (approximate).
-
-
- 2-3
- DATA ON SOLAR SYSTEM OBJECTS
- The Solar System Window lists the co-ordinates
- (in the current list frame), distances from Sun
- (rS) and Earth (rE), phases (1.0 means full disc)
- and visible magnitudes. Distances are in AU.
- The co-ordinates of Moon are corrected for the
- parallax.
- This window, accessible via <List|List Solar
- System>, does not respond to any mouse clicks
- except scrolling.
- 2-4
- THE MAP WINDOW
- This window is opened from the menu by clicking
- on <Map|Draw grid>, <Map|Draw stars>, <Map|Draw
- deep sky objects> or <Map|Draw Solar System>.
- If, when this happens, the window is already
- open, then the specified class of objects will
- be just added to the map, unless some parameters
- describing the previous contents have been changed
- (and "Map disabled" warning is being shown).
- In the latter case the window will be redrawn,
- including the grid (if not disabled from <Map|Set
- drawing mode>) and the requested objects.
- The number of the recently drawn objects is dis-
- played as the window title.
- 2-5
- DRAWING A MAP
- The redrawing uses the most recently entered map
- parameters. If these have not been changed, if the
- object selection remains the same and if the given
- class of objects is already mapped, the window
- will be just brought to the top, without drawing.
- If <Map|Selected only> is checked, then only the
- objects selected by the last select command will
- be included. The map will then need to be redrawn
- - until then search and identification of stars
- will be disabled.
- <Map|Set drawing mode> changes some of the map
- drawing defaults (grid on/off and spacing, black
- margin, magnitudes shown or not).
- 2-6
- MAP PARAMETERS - I
- Click on <Map|Set parameters> to set:
- * PROJECTION: defines how the celestrial sphere is
- projected onto a plane.
- * RANGE: from 60° to 180° across the map window,or
- Full, with the whole map fitting into the window
- * PROJECTION FRAME: coordinate system in which the
- sky will be drawn.
- * GRID FRAME: the reference system depicted by the
- grid (can be different than than the above).
- * PROJECTION CENTER: in any reference frame. Chan-
- ging the frame will re-compute the values. The
- last marker position can be chosen by clicking
- on [Last Mark] button.
- 3-1
- MAP PARAMETERS - II
- [Round] will round the center coordinates to the
- nearest whole numbers of grid steps (so it should
- be used only after the map scale is selected).
- The map is NOT redrawn after new parameters are
- entered, but only when one of the <Map|Draw ...>
- menu entries is used.
- The window info line will initially display the
- projection information, which also can be recalled
- at any time by clicking on <Map|Show parameters>.
- A double-click in the map will display the mouse
- coordinates in the grid frame. The same happens
- for a single click when no object is found under
- the mouse (see the next page).
- 3-2
- OBJECT IDENTIFICATION
- Clicking on an object in the map (or in the HR
- plot) will recall its brief data to the window's
- Info Line. The object will be marked, and <Find|
- Show again> will display its full data (except for
- Solar System objects).
- Only the first object (as currently sorted) at a
- given pixel will be identified. The Solar System
- is scanned before DSOs and stars, so if a star and
- a planet overlap, the planet will be recognized.
- Holding the Shift key when clicking on an object
- will exclude Solar System from the search.
- The identified star or DSO will be highlighted
- in its database window (if present there).
- 3-3
- FINDING AN OBJECT
- The <Find|Find...> menu entries allow to search
- for various objects, identified as follows:
- * Solar System objects: by name (or its beginning,
- like MA for Mars).
- * DSOs: by catalog number.
- * Stars: by number or by name. In the latter case
- leaving one field (symbol or constellation) em-
- pty will find the first star matching the other
- field. The others can be found with <Find|Next
- matching star>.
- The found object will be highlighted in its data
- base and marked on the map (if on top). It can be
- redisplayed in full with <Find|Recall last...>
- 3-4
- HERTZSPRUNG-RUSSEL DIAGRAM
- This diagram is plotted as M vs. B-V. By default
- M ranges from -10 to 10, and B-V - from -0.5 to 2.
- If, however, M and/or B-V limits are set in the
- listing (use <List|Select stars> to do it), then
- these limits will be imposed on the H-R plot, too.
- Stars included into the H-R plot can be limited
- to those drawn in the last map, and to those lis-
- ted in the database window; these limitations are
- toggled with <Plot|Mapped only> and <Plot|Selected
- only> menu entries, respectively.
- Star identification and search are also possible
- from the H-R diagram (see the preceding pages).
-
- 3-5
- DEFINING THE HORIZON FRAME
- Click on <Options|Set horizon frame> to set:
- - Observer's co-ordinates as dd°mm' (minutes have
- to be entered as two digits even if they are ze-
- ros); negative values denote South and West.
- - Observation date as yyyy/mm/dd (valid years:
- 1900..2100).
- - Observation time (GMT) in Star 2000 is frozen at
- 0:00 (this affects the positions of Sun and
- Moon, and, of course, limits the usefulness of
- the horizon reference frame). This limitation is
- lifted in the full version of Star Base.
- Initially, the observer position is set to Washin-
- gton, DC on 0:00 GMT, January 1, 2000.
- 3-6
- MEMORY MANAGEMENT
- If there is not enough memory for all the data,
- the program will first load the planetary data,
- then the stars and DSOs.
- The last data file may be truncated to fit into
- available memory, so it is important to know that
- stars and DSOs are stored on disk starting from
- the brightest.
- 4-1
- FILE OPERATIONS
- These operations are not available in Star 2000.
- <File|Clear data> clears all stars and DSOs from
- memory. Then new data can be read from disk, with
- an option to load just a part of the data set.
- The input filter is invoked from <File|Selective
- read>. It allows to set magnitude limits for stars
- and DSOs, and to select objects within a circular
- region. Leaving a magnitude field empty means no
- VM cut-off, while the fields for region radius and
- center coordinates should be either all left empty
- or all filled.
- The <File|Read...> menu entries allow to load
- stars and DSOs in any sequence.
- 4-2
- STAR 2000 VERSUS STAR BASE
- * Star 2000 lists 2000 brightest stars and 100
- deep sky objects; Star Base raises these numbers
- to 9096 (the full YBS Catalog) and 333; it also
- has data on comets and accepts optional (larger)
- data sets (see the previous page).
- * Star Base provides higher map magnifications:
- the smallest map range is 4° (not just 60°).
- * The Universal Time in Star Base can be set to
- any value (not being frozen to 0h00m). Time and
- date can be modified freely (not just once for
- each program run).
- * Of course, Star Base comes with a printed user
- manual and one update included in the $43 price.
