create_non_delta_rmf
(rmflo, rmfhi, fname, offset=1, e_min=None, e_max=None, ethresh=None, name='delta-rmf')[source] [edit on github]¶ Create a RMF using a matrix from a file.
The RMF matrix (the mapping from channel to energy bin) is read in from a file.
New in version 4.10.1.
Parameters: - rmfhi (rmflo,) – The energy bins (low and high, in keV) for the RMF. It is assumed that emfhi_i > rmflo_i, rmflo_j > 0, that the energy bins are either ascending, so rmflo_i+1 > rmflo_i or descending (rmflo_i+1 < rmflo_i), and that there are no overlaps. These correspond to the Elow and Ehigh columns (represented by the ENERG_LO and ENERG_HI columns of the MATRIX block) of the OGIP standard.
- fname (str) – The name of the two-dimensional image file which stores the response information (the format of this file matches that created by the CIAO tool rmfimg [1]).
- offset (int, optional) – The starting channel number: expected to be 0 or 1 but this is not enforced.
- e_max (e_min,) – The E_MIN and E_MAX columns of the EBOUNDS block of the RMF.
- ethresh (number or None, optional) – Passed through to the DataRMF call. It controls whether zero-energy bins are replaced.
- name (str) – The name of the RMF data set
Returns: rmf
Return type: DataRMF instance
