 As a detrend may be created with one det_type and det_id, but subsequently registered as another detRun, it is not generally correct to assume that the det_id and det_type listed in the filename directly match the det_id/det_type requested and used by the detrend processing.  This information is better obtained via the detselect command.
 = Detrend types =
- * DARK. Detrend to remove the camera dark current.  
- * 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.
- * 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. 
- * FLAT.  Detrend to remove the pixel-to-pixel response of the detector.
- * 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.
- * MASK. Manually constructed mask to remove bad areas of the detector.
- * VIDEOMASK.  Similar to a VIDEODARK above, but instead of correcting regions with discrepant dark current, these regions are masked out.
- * CTEMASK. Automatically constructed mask that contains information about regions with Charge Transfer Efficiency issues.  
- * FRINGE. Detrend to remove fringing patterns in the infrared.
- * LINEARITY. Manually constructed detrend listing the measured linearity response at low flux levels.
- * 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.
