Hola Frank,
Thanks for your help, it worked perfectly. I haven't realized about the asthedit functions even if I had already used it once for 'juldays' a time ago.
Thanks again, and greetings,
Cristina.

[quote:dbd62a37a9]Hola Cristina,
The task you want is ASTHEDIT in the ASTUTIL package.  The command that I think works for your data is:
as> asthedit ngc7094-001B lst.dat
as> hselect ngc7094-001B lst yes
18:52:47.74
where
as> type lst.dat
lst = mst (@"date-obs", obsdb ("osn", "longitude"))
This takes your DATE-OBS, where the time is supposed to be UT, and the information from the observatory database and computes the LST and puts it in your header as keyword LST.  I assume your observatory database has OSN since it is in the file I have here.
Let me know if you have questions or if you think this is wrong.
Yours,
Frank Valdes
