| | 28 | * DARK. Detrend to remove the camera dark current. |
| | 29 | * DARKTEST. This is an intermediate testing version of a DARK. It is constructed based on the same recipes as a regular DARK, but will not be accidentally selected for processing when finished (as processing only selects a valid DARK detrend). However, as detrends are often constructed with this det_type (and then converted to a DARK, or registered as a DARK), filenames often contain this string. |
| | 30 | * VIDEODARK. This is a special (currently theoretical) DARK that is constructed from frames that have had video data taken on a cell. This changes the electronic response of the detector, resulting in a different dark current on the images. |
| | 31 | * FLAT. Detrend to remove the pixel-to-pixel response of the detector. |
| | 32 | * FLATTEST. Similar to a DARKTEST above, this detrend is a FLAT that was constructed with a parallel name to avoid being accidentally used in processing. |
| | 33 | * MASK. Manually constructed mask to remove bad areas of the detector. |
| | 34 | * VIDEOMASK. Similar to a VIDEODARK above, but instead of correcting regions with discrepant dark current, these regions are masked out. |
| | 35 | * CTEMASK. Automatically constructed mask that contains information about regions with Charge Transfer Efficiency issues. |
| | 36 | * FRINGE. Detrend to remove fringing patterns in the infrared. |
| | 37 | * LINEARITY. Manually constructed detrend listing the measured linearity response at low flux levels. |
| | 38 | * NOISEMAP. Detrend containing the read noise values as a function of detector position. The regular noisemaps can be generated through the dettool system. We currently use boosted noisemaps that require subsequent processing to add these boosts. |
