Unless output to a separate dataset is enabled, a pair of tables named BADPIX0 and BADPIX1 are added to the input dataset, replacing any previously existing versions.
| CCDNODE | readout node identifier |
| WINDOWX0 WINDOWY0 | telemetry window origin, chip coordinates |
| WINDOWDX WINDOWDY | telemetry window dimensions |
| ABUTTED | telemetry windows abut, logical |
CHIPX
CHIPY |
int16 | chip coordinates of bottom pixel |
| YEXTENT |
int16 | upward extent in pixels |
| TYPE | int16 | bad pixel type identifier |
| BADFLAG | int16 | bad pixel source identifier |
Attributes CCDID and CCDOCB are copied from the PIXELS table of the input dataset, and attribute INSTRUME is copied from the input dataset header. The attribute ABUTTED, described above, is set true if the last column of the telemetry window for node 0 is adjacent to the first column of the telemetry window for node 1. When, as normal, the nodes do abut, any bad pixel entries in the adjacent last and first columns will be written as duplicates in both nodes. This allows the NEXT_TO_BADPIX event attribute to be set correctly in the opposing node.
When enabled this dataset is created, clobbering any previous version, and the tables named BADPIX0 and BADPIX1 are added according to the previous specification. The following attributes are also copied to the output dataset header from the input dataset header: TELESCOP, INSTRUME, OBS_ID and EXP_ID.
