I am an astrophysics student at the University of Louisville. Last semester, a third of the course was a brief introduction to reducing CCD data in IRAF and producing a spectral curve. An example was worked through in reducing Hubble data of a galaxy that the professor had written a paper on. At the time, however, I did not have a laptop yet. I now have a laptop with Linux (fedora), and I am trying to piece together what we worked on and I am not getting too far.
If you are familiar with IRAF, here is my current standing:
I have been able to combine the zero and flat images and have produced a zerocombine.fits, flatcombine.fits, and something called a flatten.fits. I was able to work through the steps that he has in his notes through apflatten although I am not sure what that did.
I have looked through user manuals and cookbooks on the subject online and get lost in the language. I am also having trouble understanding, in the list of files from the data he collected, what exactly are the longslit spectra images are exactly.
WHAT I AM REALLY ASKING...
Does anyone have any examples, or know of any online, of someone working through CCD images, combining zero and darks, correcting the images they want to reduce the spectra of, and then reducing the spectra itself? Then maybe calibrating for wavelength?
Would anyone be interested in communicating with me on maybe working out how to do that with either the example I am working on or one they might have?
Are there any other good programs for doing this?
Thanks a lot! I am really interested in developing some skills in IRAF.
