Hi guys, I need help, more specifically in a technical issue. I started my thesis with an Astrophysics professor and he gave me a topic of "M dwarf spectra with cyclotron bumps from SDSS". In short, I am given spectra of a number of cylotron bump M-dwarfs (CBMDs) from unusual quasar search from SDSS, in FITS tables format. I'm to analyze them, first by determining their types of M-dwarf and subtract them from the spectra (also check if Red Shift is significant), so I can analyze the residual - spectra of Cataclysmic variables and cyclotrons. So here is my problem - I have work with the FITS tables and I have no experience in those, and they cannot be opened in Excel. My advisor suggested me to use "ESO MIDAS", a software that can handle what I have to do - but it only works in Linux and is...in command lines, which I'm not confortable with (also it's at least 20 years old and support has been discontinued for a decade) - the reason he suggests this is because my advisor has been using for a long time and he can tell me what to do if i'm stuck - which, I clearly will be. I looked up another software called TOPCAT and it can open my tables and seems to have a number of good tools for analysis; but I have never used it before, I am not sure if it can fully do what I have to do, I have no experience on it as well as no technically support from my advisor (there are online manuals though). My advisor doesn't mind what software I use at all, I can use Excel for all he cares (but Excel can't open FITS of course), I prefer to work in Windows, with a Graphical UI instead of a command line. If there is no better option, I can either work with TOPCAT or suck it up and use MIDAS, but it will be very inefficient for me - setting up Linux with MIDAS is painful enough - the software has been discontinued for a long time... So I wonder if anyone who is familiar with this sort of thing can recommend me a software, that is simple to use and efficient? I assume what I have do is fairly simple? Just some tables and spectra to analyze with basic fitting and manipulation. Thanks for the help!
