Description

Add a spectral model constructor to the GModelSpectralNodes class that transform any spectral model into a spectral node model. The format of the constructor should be

GModelSpectralNodes(const GModelSpectral& model, const GEnergies& energies);

where the energies argument specifies the energies for which the nodes should be set.

Recurrence

No recurrence.

  • Status changed from New to In Progress

The following code works now:

>>> import gammalib
>>> m=gammalib.GModels('${CTOOLS}/share/models/crab.xml')
>>> e=gammalib.GEnergies(10,gammalib.GEnergy(0.1,'TeV'),gammalib.GEnergy(100.0,'TeV'))
>>> n=gammalib.GModelSpectralNodes(m[0].spectral(),e)
>>> print n

#2 Updated by Knödlseder Jürgen about 9 years ago

  • Status changed from In Progress to Closed
  • % Done changed from 0 to 100

I added a unit test and merged the new code into devel.
