create_energy_dispersion_hdu

pyirf.io.create_energy_dispersion_hdu(energy_dispersion, true_energy_bins, migration_bins, fov_offset_bins, point_like=True, extname='EDISP', **header_cards)[source]

Create a fits binary table HDU in GADF format for the energy dispersion. See the specification at https://gamma-astro-data-formats.readthedocs.io/en/latest/irfs/full_enclosure/edisp/index.html

Parameters:

energy_dispersion: numpy.ndarray: Energy dispersion array, must have shape (n_energy_bins, n_migra_bins, n_source_offset_bins)
true_energy_bins: astropy.units.Quantity[energy]: Bin edges in true energy
migration_bins: numpy.ndarray: Bin edges for the relative energy migration (reco_energy / true_energy)
fov_offset_bins: astropy.units.Quantity[angle]: Bin edges in the field of view offset. For Point-Like IRFs, only giving a single bin is appropriate.
point_like: bool: If the provided effective area was calculated after applying a direction cut, pass True, else False for a full-enclosure effective area.
extname: str: Name for BinTableHDU
**header_cards: Additional metadata to add to the header, use this to set e.g. TELESCOP or INSTRUME.
