irf.rmf

class ximpol.irf.rmf.xBinTableHDUEBOUNDS(data=None, keywords=[], comments=[])

Binary table for the MATRIX extension of a rmf file.

class ximpol.irf.rmf.xBinTableHDUMATRIX(num_chans, data=None, keywords=[], comments=[])

Binary table for the MATRIX extension of a rmf file.

class ximpol.irf.rmf.xEnergyDispersion(mrf_file_path)

Class representing the energy dispersion.

Parameters:rmf_file_path (str) – The path to the .rmf FITS file containing the energy dispersion tables.

view(show=True)

Plot the energy dispersion.

class ximpol.irf.rmf.xEnergyDispersionBounds(hdu)

Class encapsulating the bounds for the energy dispersion matrix, as stored in the EBOUNDS extension of a .rmf file.

class ximpol.irf.rmf.xEnergyDispersionMatrix(hdu, num_aux_points=200)

Class encapsulating the energy dispersion matrix, as stored in the MATRIX extension of a .rmf file.

In order to streamline performance, the energy grid is down-sampled to the value of the num_aux_points parameter, in such a way that the xUnivariateAuxGenerator.build_vppf()` doesn’t take forever.

Parameters:

• hdu (FITS hdu) – The MATRIX hdu in the .rmf FITS file.
• num_aux_point (int) – The number of points that the energy dispersion matrix should be down-sampled to.

Warning

If the value of num_aux_points is too small, then the two-dimensional underlying spline tends to have blob-like features, and the vertical slices are no longer necessarily accurate representations of the energy dispersion. We should keep an eye on it.
