Pure vignetting by the average of three runs with different orientation of the camera.
Pictures of white light illuminated noise of the wall in Frascati lab by @davidepinci .
Average of 3 orientations are taken to move away the neon lines.
The measurement is done with ORCA flash (2048 x 2048). The vignetting map is the following:
1D profile is the following:
Since the vignette is perfectly circular, the 1D profile is stretched to 2304 pixels and used to make a vignette map for LIME (2304 x 2304). This has a perfect circular symmetry by construction.
Everything is in the same input file (data/vignette_runs03930to03932.root) and it is automatically taken when giving the geometry (lime or lemon) in the configFile.txt
@gdimperi This is pure vignetting map (no field, gas effects, etc).
Keeping the effective map in data/vignette_run03806.root, but this for sure is affected by the light in the top of the sensor.
@davidepinci @gianlucacavoto now reconstructing Fe55 runs with this correction.
