Hi there,
I have a problem using the wspectext utiliy on an ESO fits file. The thing is that hselect sems to be missing :
What can I do about it. I also try to specify 'header = no' but nothing changed.
Is the hselect task really missing ? Is there a simple way to install it ?
Thank you for your help
(I'm kind of a novice at IRAF)

ERROR: task `hselect' not found

line 21: onedspec$wspectext.cl
called as: `wspectext (input=Hip044105calib.fits, output=Hip044105calib.dat)'
What can I do about it. I also try to specify 'header = no' but nothing changed.

Hello,
HSELECT is a core task and so cannot be missing if you can run IRAF at all.
The usual login.cl created by the mkiraf command loads the commonly used packages. But it is possible you are doing something differently; such as not
having a login.cl file or starting IRAF from a directory different from where your login.cl file is located. In that case you need to load the "images" package to access the hselect task. This is the only possibility I can think of.
If this is the case because you are just learning then you should use mkiraf in some directory that will be your IRAF "home" so that things are setup in a reasonable manner. You can start IRAF from other directories but then some things will not work conveniently.
Let us know if loading the images package manually does not solve the problem.
Yours,
Frank Valdes
