Description

The following commands that provide an invalid IRF result in an error message that is not very informative. Proper checking of the IRF existence should be implemented.

$ ctobssim
RA of pointing (degrees) (0-360) [267.68]] 83.63
Dec of pointing (degrees) (-90-90) [-29.6] 22.01

I added some code to the CTA response loader methods that first checks whether the response files do exist. Now, the above example gives the following result:

$ ctobssim
