Note
The following shows the code used to run this marx test. You can inspect
it and adapt it to your needs, but you cannot copy and paste it directly
because it depends on local $PATH and other environment variables.
For example, we use a python function to manage the directory structure
for all the images generated by all the tests instead of giving the file
name directly to save images.

shell : Unzip fits file.¶
MARX cannot read zipped fits files, so we need to unzip the .fits.gz asol files that we downloaded from the archive. On the other hand, CIAO tools work on both zipped or unzipped files, so there is no need to unzip all of them, just the files that MARX reads as input.

CIAO : Create exposure maps¶
Also, make exposure map for S-3 chip to correct for dither etc. Mirror effective area is not included in that calculation, because all the photons we care for come from the same source, not from different positions on the sky, thus the mirror effective area is the constant for the source we look at.
The instrument map depends strongly on the energy. We will thus pass in the source spectrum. This gives us one map appropriately scaled for the whole spectrum. However, in later analysis, we want to split the data in narrower bands. When looking at that accurately, we need to have one map for each band.
Also, the observed data contains bad pixels, while the marx simulated data does not. This means that we need to make a second set of maps with no bad pixels in them.

Python : Clean bogus sources from src file and write regions¶
celldetect always detects plenty of sources on the read-out streak and around the piled-up regions. For processing speed and clarity we want to remove those bogus detections from the source list.
# Note that this code might not run if you directly copy and paste it:
# - Not all import statements are shown here
# - `self` is a reference to a test instance, which allows access to
# parameters such as the directory where the test is run etc.
