wcsDetectorPointingResidual double arcsec Maximum difference (on the pointing-fit grid) between the final WCS position and the position predicted by camera geometry, after re-pointing using the final WCS for this detector only. The detector is rejected from the pointing fit if this exceeds 10". 500
wcsVisitPointingResidual double arcsec Maximum difference (on the pointing-fit grid) between the final WCS position and the position predicted by camera geometry, after re-pointing using the final WCS of all non-rejected detectors in the visit. The WCS is set to null if this exceeds 60". 510
wcsPreliminaryDetectorPointingResidual double arcsec Maximum difference (on the pointing-fit grid) between the preliminary WCS position and the position predicted by camera geometry, after re-pointing using the prelimnary WCS for this detector only. The detector is rejected from the pointing fit if this exceeds 10". 520
wcsPreliminaryVisitPointingResidual double arcsec Maximum difference (on the pointing-fit grid) between the preliminary WCS position and the position predicted by camera geometry, after re-pointing using the preliminary WCS of all non-rejected detectors in the visit. The WCS is set to null if this exceeds 60". 530
shapeletsIqScore double The dimensionless image quality score as determined from the shapelets decomposition that includes power from the median centroid offset between those used in the decomposition and those of the centroid slot in addition to non-atmospheric decomposition coefficients. The score spans the range [0.0, 1.0] with lower values indicating better image quality. 540
centroidDiffShapeletsVsSlotMedian double pixel Median centroid difference (sqrt((slot_x - shapelet_x)**2 + (slot_y - shapelet_y)**2)) for sources used in the shapelet decomposition. 550
shapeletsStarEMedian double Median ellipticity (sqrt(starE1**2.0 + starE2**2.0)) of the sources used in the shapelet decomposition. 560
psfAdaptiveIncludeThresholdMultiplier double Threshold multiplier used in the adaptive threshold detection pass for PSF modelling. 570

psfAdaptiveThresholdValue double Threshold value used in the adaptive threshold detection pass for PSF modelling. 600
shapeletsOnlyIqScore double The dimensionless image quality score as determined from the shapelets decomposition that includes power only from the non-atmospheric decomposition coefficients. The score spans the range [0.0, 1.0] with lower values indicating better image quality. 610
nShapeletsStar int Number of sources used in the shapelet decomposition. 620
