make_psf

gammapy.irf.make_psf(observation, position, energy=None, rad=None)[source]

Make energy-dependent PSF for a given source position.

Parameters:
observation : DataStoreObservation

Observation for which to compute the PSF

position : SkyCoord

Position at which to compute the PSF

energy : Quantity

1-dim energy array for the output PSF. If none is given, the energy array of the PSF from the observation is used.

rad : Angle

1-dim offset wrt source position array for the output PSF. If none is given, the offset array of the PSF from the observation is used.

Returns:
psf : EnergyDependentTablePSF

Energy dependent psf table
