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.

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
