Testing gammapy following templates showed during the call of 8/10/2020 in the Notebooks by Atreyee Sinha https://github.com/AtreyeeS/test_notebooks/tree/master/lc
To implement the power law temporal model, I have modified the "opt/miniconda3/envs/gammapy-0.17/lib/python3.7/site-packages/gammapy/modeling/models/temporal.py" file by adding a new class called "PowerlawDecayTemporalModel"
The code does not work when simulating data, I don't understand why...
