Description
Following a recent modification in GModelSpatialDiffuseMap
the values returned by the GModelSpatialDiffuseMap::mc
method are limited to the simulation cone region. This implies however that for maps that are larger than the simulation region there are too much events simulated (as there are never events falling outside the simulation region).
The flux normalization seems also to have disappeared.
Recurrence
No recurrence.

Reintroduce flux normalization of map.
Compute now the Monte Carlo normalization as the fraction of the flux that is comprised within the simulation cone. At a first glance this produces the expected results, but we now have to redo all the pull distributions to see whether the results are okay.

Here now pull distributions for three cases: an ROI of 6°, an ROI of 7° and a tiny map (from top to bottom). All look fine.
We now need to check also whether ROI’s smaller than the map work and we should also verify that non-normalized maps work.

Below are pull distributions for a ROI that is smaller than the map size (top row), and for a ROI that is smaller than the map size and no map normalization (bottom row). Everything looks okay.
