I adapted the script so that it can also handle On/Off data. This needed some minor changes in GammaLib, and in particular, the addition of a PHA, ARF and RMF constructor to GCTAOnOffObservation.
Below a comparison spectrum for a simulated 30 min Crab observation. Red are the spectral points obtained with csspec, blue the spectral points obtained using an unbinned analysis without energy dispersion, and green the spectral points obtained using an unbinned analysis with energy dispersion. Note that for a On/Off analysis, energy dispersion is always included.
The spectra are pretty consistent, and the error bars are larger for On/Off with respect to an unbinned analysis as expected from the larger uncertainty in the background model.
