Description
Some low-level functionalities are needed to support the creation of csresspec ([[https://cta-redmine.irap.omp.eu/issues/2289]]):
- collapse GSkyMap over spatial dimensions to produce energy array
- extract Gamma and Background Counts (TBD)
Recurrence
No recurrence.

Updated by Knödlseder Jürgen over 6 years ago
- Target version set to 1.5.0

Updated by Tibaldo Luigi over 6 years ago
- Status changed from New to In Progress
- % Done changed from 0 to 70
Implemented:
- in GSkyMap: total_counts and total_flux methods to sum or integrate over a map/set pf maps
- in GCTAOnOffObservation: model_gamma and model_background that given a model container return a Pha object with the corresponding predicted counts for the observation; this required to excise the WSTAT likelihood profiling out of the full likelihood_wstat function (wstat_value), so that it can be used to derive the background counts for WSTAT for a single bin without all the other tasks to do an optimization (Hessian, etc).
All that is needed for csresspec is in place, but I’ll leave this open in case anything else pops out.

I merged the code into devel.
I renamed the methods GSkyMap::total_flux() and GSkyMap::total_counts() to GSkyMap::flux() and GSkyMap::counts() since a GSkyMap::flux() method with different arguments existed already, and the current GammaLib logic is to overload methods with the same name if they provide the same kind of functionality.
