ctools

When running a cscript from within python, e.g.

import csresmap
resmap = csresmap.csresmap()

The above code will throw an error due to the following line of code int the cscripts:

if isinstance(argv[0],gammalib.GObservations):
            self.obs = argv[0]
            argv     = argv[1:]

It has to be assured that len(argv)>0 first! the following cscripts are affected:

• csresmap
• csspec
• cslightcrv
