- SkyMap Release History
- ----------------------
-
-
- 05-Feb-93 v1.11
-
- When the start of a constellation figure was off the edge of the map,
- the first visible line of the constellation was being drawn incorrectly in
- certain circumstances. Fixed.
-
- The correction for refraction was being correctly calculated and correctly
- displayed in the "About" box for a star, but not applied to the plotted
- position of the stars on the map. This led to stars being plotted with
- slightly too low an altitude (the maximum error being about half a degree
- at the horizon). Fixed.
-
- If the star position calculation was aborted by the user pressing the "Cancel"
- button, the subsequent constellation figure setup calculation code displayed
- an error message for each star it was unable to find. Pressing the "Cancel"
- button now aborts the map calculation cleanly.
-
-
- 31-Jan-93 v1.1
-
- Test release to BIX only for testing.
-
- In the "Observer" dialog, the "Time Difference" edit field was only wide
- enough to allow two digits to be entered, making the program not too
- useful for anyone outside the GMT time zone. Fixed.
-
- Version 1.0 of SkyMap simply plotted stars in their mean catalog position.
- This version now rigorously calculates the apparent place for the time of
- observation, correcting for proper motion, aberration, precession, nutation,
- and refraction.
-
- Added code to verify that dates are in the range 4000BC-8000AD (the
- range over which the planetary position equations are valid.
-
-
-
- 24-Jan-93 v1.0
-
- Release of SkyMap 1.0, with basic facilities for drawing horizon map and
- plotting planetary and lunar positions.
