I'm trying to view raw multifiber spectra. I would like to extract the 1d spectra from the 2d spectra. It would seem as though [i:e2072ca838]apall[/i:e2072ca838] would be the task to use. However, I receive the following error: ERROR: FXF: must specify which FITS extension. I can't seem to find anything in the help file for apall or on the net about the solution to my problem. Any ideas?

It's nothing peculiar to APALL, the message just means that you have a Multi-Extension FITS file and so need to specify the image extension to use, e.g.[code:1:ca151ea4c8] cl> imstat mef.fits[1][/code:1:ca151ea4c8]You can read more about the FITS kernel usage at https://iraf.net/irafdocs/fits_userguide/-Mike
