On apps2:

Open up a terminal of your choice and change current working path to "/home/kurpitsa/contobs/". Backup sources.list with "mv sources.list sources.list_YYYYMMDD" (where YYYYMMDD should of course reflect the current date) and run "./muunna". Follow "In vax"-instructions.

In vax:

Our "master source list" with the correct J2000 coordinates is called gix_sources.list. The sources.list is converted from this by typing:
The program asks for the initial epoch, which for this case is J2000, ie. answer 2.
Then it asks for the final epoch, and if you make the conversion for "your" week, it is a good idea to use a date from the middle of the week. For example for week 28 it would be something like: Then give the file names: And that's it. CONTOBS will immediately start using the newest version of the sources.list file.
