ASTHEDIT and keywords containing “-“

athlonea wrote on Jul 06, 2007

Hi there,

I've been trying to add a number of keywords that are not added automatically by my CCD software to FITS headers using ASTHEDIT and a configuration file, however there is a problem with DATE-OBS keyword. It seems it's because of "-" (when added with HEDIT, it works fine).

Is there any way to add keywords containing "-" (and probably other characters that are neither letters nor numbers) with ASTHEDIT?

Thanks for any help,

ath

See the help page for examples, but I think you need to use the '@' sign before the quoted keyword so it is interpreted correctly, e.g. @"date-obs" This is used to de-reference the value, otherwise the '-' is taken as an operator to compute the difference between the values of the 'date' and 'obs' keywords.

Cheers,
-Mike

I could not find it among the examples in ASTHEDIT help, but I tried using @ and it worked perfectly...

Thanks a lot for help :)
