| Header Keyword | Description |
| CTE_NAME | Name of CTE algorithm. |
| CTE_VER | Version of CTE algorithm. |
| PCTETAB | File containing CTE correction parameters. |
| PCTERNCL | PCTE read noise level. Default value is 5.0. |
| PCTENSMD | Read noise mitigation mode. Possible values: |
| 0 (no smoothing) | |
| 1 (normal smoothing, default) | |
| 2 (strong smoothing) | |
| PCTETRSH | Pixels taken below this threshold by CTE correction are re-corrected with a smaller correction. Default value is -10. |
| PCTESMIT | PCTE readout simulation iterations. |
| PCTESHFT | PCTE readout number of shifts. |
| PCTEFRAC | CTE time scaling value. |
The PCTETAB reference table, as well as the DKC files, are now listed on the ACS Dynamic Reference file pages.
