installation :
- copy ephem or ephem881 to your execution directory. ephem881 can be renamed
to ephem (both module names are 'ephem').
- the environnement variable TZ has to be set.
for central europeen time : setenv TZ CET (see also the C users manual
under 'time()'). the best would be to set it in your .login file.
- copy ephem.cfg and ephem.db to /dd/SYS. in ephem.cfg you can configure
your geographical position. for more information see the file 'ephem.doc'.
if you want to have your own configuration file, you can have it in your
local directory called 'ephem.cfg' or in your hame directory called
'.ephemrc'. It's also posiible to specify the file on the command line
( ephem -c <filename> ).
the files are searched in the following order :
1. -c <filename>
2. ./ephem.cfg
3. getenv("HOME")/.ephemrc
4. /dd/sys/ephem.cfg
if one of the files is found it is read and the search will be aborted.
it is similar for 'ephem.db' :
1. -d <filename>
2. getenv("EPHEMDB")
3. ./ephem.db
4. /dd/sys/ephem.db
- ephem.doc is the full documentation for the program and should be read to
understand the funcionality of the program.
