- Description updated (diff)
You can do
>>> map=gammalib.GSkymap("CAR","CEL",0.0,0.0,1.0,1.0,10,10)
>>> map[0] = 3.4
>>> map[0] *= 2.0
>>> print(map[0])
6.8
Or are you looking for something else?

just a function to automatically scale each pixel by a constant.
It’s not necessary since we can always go to each pixel and do what you described. You can reject this issue if you don’t like to have such a function.

I added the operators
GSkymap& operator*=(const double& factor); GSkymap& operator/=(const double& factor);
to
GSkymap that allow multiplication or division of all pixel values by a given factor.
