Input Files

The following input files are never modified by this task.

• evlist — filtered event dataset (rgsfilter)

  Attributes: TELESCOP, INSTRUME, FILTER, OBJECT, OBS_ID, EXP_ID, EXPIDSTR, DATE-OBS, DATE-END, EQUINOX, RADECSYS.

  Extensions:

  • EVENTS

    Attributes:

    SOURCEID	int	aspect correction target source index
    RA_OBJ DEC_OBJ

    Columns:

    PI	short	calibrated energy
    BETA_CHANNEL XDSP_CHANNEL	short	channel coordinates

    These WCS attributes of the channel columns are also required: TCDLT, TCRPX, TCRVL, TLMIN and TLMAX.

  • EXPMAPnn

    At least one valid exposure map extension is required. To be considered valid an exposure map must cover a non-zero area on a channel grid commensurate with the channel grid of the EVENTS table.

    Attributes:

    CCDNODE	int	readout node identifier
    DATAMAX	real	maximum duration of exposure
    CTYPE1 CUNIT1 CRPIX1 CRVAL1 CDELT1	WCS	dispersion axis
    CTYPE2 CUNIT2 CRPIX2 CRVAL2 CDELT2	WCS	cross-dispersion axis

• srclist — source definition dataset (rgsregions)

  Extensions:

  • SRCLIST

    Attributes:

    INSTRUME

    string

    instrument

    Columns:

    INDEX	int	source identifier
    DELTA_DISP	real	grating dispersion angle

  • $<\!\!instrument\!\!>$_BACKGROUND

    FITS region in RGS angular coordinates: defines the background spatial selection region. This region is never required in HTR mode, and in Spectroscopy mode it is not required for a TOTAL spectrum.

  • $<\!\!instrument\!\!>$_SRC $<\!\!source\!\!>$_SPATIAL

    FITS region in RGS angular coordinates: defines the source spatial selection region. This region is always required in HTR mode, but in Spectroscopy mode it is not required for a BKG spectrum.

  • $<\!\!instrument\!\!>$_SRC $<\!\!source\!\!>$_ORDER_ $<\!\!order\!\!>$

    FITS region in RGS dispersion and energy (PI): defines the source energy selection region. This region is always required in Spectroscopy mode, but in HTR mode it is not required for a BKG spectrum.

  • $<\!\!instrument\!\!>$_SRC $<\!\!source\!\!>$_ORD $<\!\!order\!\!>$_BKG

    FITS region in RGS dispersion and energy (PI): defines the background energy selection region. This region is never required in Spectroscopy mode, and in HTR mode it is not required for a TOTAL spectrum.
