Delon catwise_2020, catwise_prelim WISE desc-asce ecliptic longitude real 4 arcsec    
DelonSig catwise_2020, catwise_prelim WISE one-sigma uncertainty in Delon real 4 arcsec    
Delon may have a bias correction for a systematic error induced by residual PSF errors that manifest themselves in ascending-descending differences; see the "-pb" command line option of the mrgad program. Delon is defined as descending position minus ascending position in order to have the proper sign for parallax (∼ Delon/2). Delon is the straightforward difference in ecliptic longitude, ignoring the different effective observation epochs of ascending and descending scans; Delon will be null unless ka = 3.

deprecated Multiframe VULCANiDR Code for a current (=0) or deprecated (!=0) multiframe smallint 2   0 meta.code
The deprecation attribute in all tables indicates if the record in question (be it an image or catalogue detection record) has been deprecated by some curation process in the archive. All data having deprecated=0 are nominally good data; the following flags indicate a quality issue and any data having those flags should not be used for scientific purposes (in many instances, deprecated data will be deleted from public survey released database products):
FlagMeaning
1 Stack frames that have no catalogue or other frameTypes deprecated at ingest (e.g. because a reprocessed frame supercedes it)
2 Dead detector frames
3 Undefined and or non-sensible critical image metadata attributes
4 Sky subtraction not OK (via pipeline sky sub scale factor) NB. not used from October 2005 onwards
5 Incorrect combination of expTime,numExp,numInts for survey specific projects
6 Incorrect frame complements within groups/nights (for incomplete MSBs)
7 Undefined values of critical catalogue attributes for stacks
8 Seeing=0.0 for a stack
9 High value of sky that compromises the depth, or otherwise invalid sky level (e.g. sky < 0)
10 Seeing outside specified maximum
11 Photometric zeropoint too bright
12 Average stellar ellipticity too high (> 0.25)
13 Depth (as calculated from sky noise and 5sigma detection in fixed aperture) is too shallow compared to overall histogram distribution (i.e. shallower than ~0.5mag wrt the modal value) OR sky noise is too high given the sky level
14 AperCor3 outlying in aperCor3 versus seeing distribution
15 Pipeline MAGZPT inconsistent between image PHDU, extension HDUs and/or catalogue extension HDUs (from attributes photZP, photZPExt and photZPCat)
16 Difference in detector sky level wrt to mean of all 4 detectors is outlying in the distribution of the same.
18 Provenance indicates that a constituent frame of a combined frame product includes a deprecated frame.
19 Inconsistent provenance for a stack or leav product indicating something wrong with the image product (usually screwed up FITS keywords confusing the pipeline)
20 Detector number counts indicate some problem (loads of crud images)
21 5-sigma depth of detector frame more than 0.4mag brighter than modal value for a given filter/project/exposure time
22 Basic astrometry check (pixel size and/or aspect ratio) indicates something is wrong with the image
26 Deprecated because frame is flagged as ignored in pipeline processing
27 Deprecated because frame is flagged as part of a summit-rejected MSB
40 Science (*stack) frame is not part of a survey (e.g. high latitude sky frames in the GPS)
60 Eyeball check deprecation - trailed
61 Eyeball check deprecation - multiple bad channels
62 Eyeball check deprecation - Moon ghost
63 Eyeball check deprecation - Sky subtraction problem
64 Eyeball check deprecation - Disaster (catchall category for the indescribable)
65 Eyeball check deprecation - Empty detector frame
66 Eyeball check deprecation - Flat field problem
67 Eyeball check deprecation - Malfunction in crosstalk correction
70 Eyeball check deprecation, but this is the best that can be done so should not be reobserved (e.g. very bright star in FOV)
80 Deprecated because observation (MSB,object,filter) has been repeated later (shallow surveys only). The latest duplicate in each case is kept
81 Deprecated because observation (MSB,object,filter) has been repeated in a later Semester (shallow surveys only). The deepest duplicate in each case is kept
99 Manually deprecated because of some DFS issue (e.g. pipeline screw-up)
100 Multiframe deprecated because all detectors have been previously deprecated (and the MF not already deprecated)
101 MultiframeDetectors deprecated because parent Multiframe is deprecated (and the MFD not already deprecated)
102 *Detection deprecated because parent MFD deprecated
103 MultiframeDetector of a stack deprecated because all constituent frames of the same detector are deprecated
110 Intermediate stack frame photometry found to be poor wrt run of all stacks in a deep field
111 Stack replaced by a filtered version
127 Unwanted frame ingested.
≥128 Frame deprecated because reprocessing supercedes it

Note: for deprecation values of 128 or greater, the most significant bit of the byte has been set in order to preserve the deprecation value set by any previous quality control flagging run on the previous processed version.
