Pertinent Interacting binaries:
From a slide from Paula Szody from the event The Eventful Universe.

Some spectra and lines:
From (Carter et al. 2014):
1RXS J062518.2+733433: A new intermediate polar with He lines
Space Telescope Science Data Analysis System (STSDAS)
I installed the Space Telescope Science Data Analysis System as part of iraf to try to plot the spectra. Also a reminder to use IRAF in python or ipython do:
from pyraf import iraf
iraf.<routine>
IRAF label pictures
It can be done with the option l with the specplot in noao.onedspec.
To save use implot:
implot <fits> dev=eps ; gflush
