I am doing some correlation studies and for that I need to perform fermi likelihood spectral fitting for observations in 10-12 days duration. I want to repeat the same for many observations at different epochs.
Which method is suitable for my purpose?
Python Unbinned analysis or Fermipy package?
I am doing analysis on the data of 3C 279 . So do I need to free parameters of 3c 273 which is near to this?
In the energy energy 1000-30000 , which model spectral model is perfect for 3c 279, Logparabola or simple powerlaw?
