Having a problem using the apall routine as outlined in the IRAF guides. When I read in an image and go on to define apertures, the routine seems to be plotting a spectra rather than a pixel count in the y direction.
Basically it looks to me that the x and y axis are backwards to what IRAF expects them to be. And without it being the right way, It cant extract the spectra.
Any suggestions on how to fix this would be really good. Seems odd that IRAF defaults to having dispersion vertical on the ccd and spacial dispersion on the horizontal plane. I thought most CCD's were the other way around as is mine.
Another issue now is that i save the aperture details for use on the next ccd image.
$ apall a2600265.fits ref=database/apa2600263
And i get an error saying that Refernce apertures cannot be found. I'm following a guide. So I dont think its something I have done wrong. Its definitely written the file from the previous CCD image to database/apa2600263
