Data reduction (DL3 to DL4)

Introduction

The gammapy.makers sub-package contains classes to perform data reduction tasks from DL3 data to binned datasets. In the data reduction step the DL3 data is prepared for modeling and fitting, by binning events into a counts map and interpolating the exposure, background, psf and energy dispersion on the chosen analysis geometry.

Background estimation

• FoV background
• Reflected regions background
• Ring background
