The following input files are never modified by this task.
Attributes: TELESCOP, INSTRUME, FILTER, OBJECT, OBS_ID, EXP_ID, EXPIDSTR, DATE-OBS, DATE-END, EQUINOX, RADECSYS.
Extensions:
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.
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 | 
Extensions:
Attributes:
| INSTRUME | string | instrument | 
Columns:
| INDEX | int | source identifier | 
| DELTA_DISP | real | grating dispersion angle | 
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.
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.
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.
