Meta Index / Home Page / Description

FITS file position IO.

If positions are supplied in a FITS table, specified by the parameter intable, the transformed positions are written to the FITS table designated by outtable. intable and outtable may be the same table. The task looks for the sky-position information stored in decimal degrees in columns named RA and DEC. If uncertainties are desired, esky2det looks by preference for data of the same format in RA_ERR and DEC_ERR columns; if neither column is found, esky2det looks for a common value in arcseconds stored in a column named RADEC_ERR. This last is to cater for the format of source lists output by emldetect. The transformed values are written to the appropriate subset of columns RAWX, RAWY, CCDNR, RAWX_ERR, RAWY_ERR, DETX, DETY and DET_ERR.

Null values are written (with a warning message) for sources which are outside the field of view or, in the case of RAWX/Y, not located on a ccd.
