X-ray spectra for galaxy or galaxy group in a Chandra observation of MACS J0717.5+3745

These are the data files needed to follow along with the spectral analysis I do to determine the physical processes causing the emission from the galaxy, or group of galaxies, at RA=7h 16m 44.3s and Dec=+37d 39' 56'' (J2000), from the Chandra observation of the galaxy cluster MACS J0717.5+3745 (the cluster and group are physically unrelated). The fit_group.py script fits the data using the Sherpa fitting and modelling environment, which is part of the CIAO analysis package. It's use is described in the research blog.
