Dear,
Hello, I am having the following problem, I am trying to get a 1-dimensional spectrum from a 2-dimensional spectrum, already calibrated by wavelength. The issue comes that the routine apall is not extracting the whole spectrum. It only extracts the first 980 pix from the image. However, I am working with images that they have about 1500-1800 pix length. I think this is weird, because when I do the trace of the spectrum, the routine detects the whole spectrum, but the final 1-dimensional spectrum is shorter in length. Indeed, this issue is frustrating because I am losing important info of my objects towards the redder wavelength. I hope somebody could help me.
Thank before hand. Kind regards.
Jorge.
