Reformat the detector response and energy bounds information provided by the CAL for the given instrument, corrects for instrumental effects specific to the event selection criteria used and writes the result to a specified dataset (the Redistribution Matrix File or RMF). The dataset conforms to the OGIP standard ().
The RMF matrix generated by rmfgen describes the response of the instrument as a function of energy and PI channel; PHA channel responses can not be generated by this task.
This dataset can be used in conjunction with the Ancillary Response File (ARF) dataset (generated by arfgen) to perform spectral analysis, the most commonly used analysis package being XSPEC.
Note that details of individual CCF constituents and how the CAL processes such data are beyond the scope of this document, and the reader should refer to the Calibration Access and Data Handbook for such information ().
The following list summarises the current and planned features of rmfgen:
|1||Grouping of response data above a threshold value||implemented|
|3||Spectrum-response channel range matching||implemented|
|4||Observing mode dependence||implemented|
|5||Spatial dependence and averaging||implemented|
|6||User-defined energy grid||implemented|
|7||DSS support (including eg pattern selection)||implemented|
|8||Modelling for spectral distortion due to pile-up||initial implementation, not available|
|9||Modelling of spectral distortion due to Charge Transfer Inefficiency (CTI)||to be coded|
Items 1-7 are described in more detail below. The remaining items are discussed in the future developments section ().
