Description

To compute residual maps, the simple operations to subtract two sky maps would be easy to implement. Doing so, we could add further mathematical operators like “plus”, “division”, and “multiplication”.
We could also add functions which scale the entries of the map by a factor or take the square root of it.

Recurrence

No recurrence.

I’ve added functionality supporting *= and /= operators, as well as the friend sqrt function.
The branch is in the central repo, called 1247-add-operators-and-friends-to-GSkymap

I was about to merge in your change, but I recognized that there is some change in GModelSpatialRadialGauss. Any clues where this change comes from?

 double GModelSpatialRadialGauss::theta_max(void) const
 {
     // Return value
-    return (sigma() * gammalib::deg2rad * 5.0);
+    return (sigma() * gammalib::deg2rad * 1.7941227);
 }

oups, I might have played around with this value to check the computation time in the past. I don’t know why this has been checked into repository at all. So you can just drop that. Sorry for the confusion
