Galactic latitude and Source Cuts

Galactic latitude selections

Once good Fermi data in the desired energy range is selected, we proceed to narrow our focus on photons with galactic latitude b above 50deg or below -50deg. The following Python script accomplishes this goal: Media:bcut.py

Removing regions around Fermi sources

We use the First Fermi-LAT Catalog of Sources above 10 GeV (1FHL). (Note that this is not the 1st-year Fermi catalogue, and it is actually more recent than the 2nd-year Point Source catalogue. See the link for a description).

The following Python script does the job: Media:nosource.py
