Detector Response Matrix

The IC file JMXi-RMF-GRP.fits is a grouping table with three children: JMXi-RMF.-RSP, JMXi-FBDS-MOD and JMXi-AXIS-ARF.

JMXi-RMF.-RSP is the standard detector response normalized to the sum of 1.0 over the detector channels, see Table 39 for more details.

Table 39: Content of JMXi-RMF.-RSP Data Structure.

Column	Description
ENERG_LO	Low energy bound of the energy bin, keV
ENERG_HI	High energy bound of the energy bin, keV
N_GRP	Number of channel subsets for the energy bin
F_CHAN	First channel in each subset for the energy bin
N_CHAN	Number of channels within each subset for the energy bin
MATRIX	Response values for each channel subset for the energy bin

JMXi-AXIS-ARF contains ancillary response information for an on-axis source in the JEM-X field of view, see Table 40 for details.

Table 40: Content of JMXi-AXIS.-ARF Data Structure.

Column	Description
ENERG_LO	Lower energy boundaries of bins
ENERG_HI	Upper energy boundaries of bins
SPECRESP	Effective area in cm of the detector for a given source taking all effects into account

JMXi-FBDS-MOD holds the electronic channels of the detector in Full Imaging Mode. This data structure is a copy of the data structure with the same name in JMXi-IMOD-GRP.fits (See Tables 33 and 38). It is simply repeated for completeness.
