ctools

this may be solved by issue #1360

I guess you’re talking about the Python interface, right?

You can do that already now by specifying

sim = ctools.ctobssim(gammalib.GObservations("my_observations.xml"))

sim = ctools.ctobssim("my_observations.xml")

Alternatively, we could add a parameter that allows specifying an XML file so that ctobssim could also be used from the command line to simulate multiple observations at once (this is not possible now). Maybe we want to have both options.

In the long run I was planning to add a pointing simulation step before ctobsim (something like ctpntsim) that sets up a realistic pointing sequence, taking into account realistic constraints due to site location, zenith angle of a source at a given epoch, etc. This tools would probably produce an XML file that then needs to be fed to ctobssim.

Actually, I was talking about the command line. If a user wants to simulate from a given XML file containing several observations, it would be easier to query for such an observation definition file.
Having this additional option would also make the observation setup more homogenous throughout the ctools.

Okay, then I propose to add a inobs parameter that should be queried, but that by default will be NONE.

I guess this issue is solved if we take into account the changes from #1360
