rgsspectrum (rgsspectrum-2.9) [xmmsas_20211130_0941-20.0.0]


Output Files

The output files are spectra in OGIP-compliant format (OGIP Memo OGIP/92-007). In addition to the mandatory attributes, the following non-standard attributes are provided for use by rgsfluxer and rgsrmfgen:

SOURCEID int source identifier
RFLORDER int reflection order
LINE_SEP real [Angstroms] grating line spacing
RGSALPHA real [radians] grating incidence angle

These columns are provided for all spectra, regardless of type:

CHANNEL short dispersion channel number
COUNTS int number of selected photons
QUALITY short data quality flag
AREASCAL real full exposure correction factor
FRAC_EXP real average exposure correction factor (optional)

In addition to these, for TOTAL and BKG spectra only the BACKSCAL column is provided, and for NET spectra only the STAT_ERR column is provided:

BACKSCAL real background scaling factor
STAT_ERR real statistical error
