Description

The GCTAAeff class should provide an abstract interface for the CTA effective area.

Implementations of this class should read effective area data in various formats, such as performance files, ARFs, and IRFs in CALDB format.

Recurrence

No recurrence.

I just implemented and committed (hess branch) an initial version of the abstract base class GCTAAeff and the implementation GCTAAeff2D.

The abstract base class GCTAAeff defines the general interface to a CTA effective area response.

GCTAAeff2D implements a 2D response format, where effective area is given as function of energy and offset angle. The class makes use of GCTAResponseTable which implements an interface to the Fermi/LAT like response functions. The GCTAResponseTable implement bi-linear interpolation in log10(energy) and offset angle.

Implementation of other effective area interfaces are still missing. We want to read Konrad’s performance tables (GCTAAeffPerfTable) and 1DC ARF files (GCTAAeffARF).

The loading of the effective area should be done by the GCTAResponse class. As we do not anticipate for now that external response functions are use, we probably do not need a registry for the derived GCTAAeff classes.

Note:
We may think now of moving GCTAResponseTable to the GammaLib core as GResponseTable, because the format is used by different instruments.

The GCTAResponse class has been reworked to handle the effective area classes.
