This page describes the contents of the PanSTARRS-1 database object and detection tables that contain data from some bad skycells. These tables are identical in structure to the main tables (e.g, ObjectThinBadSkycells has the same columns as ObjectThin). They include information on sources that are identified as bad in the PS1 DR2 data release because there was a problem with alignment of some images near the north equatorial pole that led to poor photometry and astrometry. We have marked the photometric measurements as bad for these objects in the main database tables, but the original information is available in these bad skycell tables.
Note that these values are considered of very poor quality, so they should be used with great caution.

ObjectThinBadSkycells
Description: Contains the positional information for objects in a number of coordinate systems. The objects associate single epoch detections and the stacked detections within a one arcsecond radius. The mean position from the single epoch data is used as the basis for coordinates when available, or the position of an object in the stack when it is not. The right ascension and declination for both the stack and single epoch mean is provided. The number of detections in each filter from single epoch data is listed, along with which filters the object has a stack detection. References: Szalay, A. S., Gray, J., Fekete, G., et al. 2007, arXiv:cs/0701164. Note that as of June 2022 the raMean and decMean positions have been updated using Gaia EDR3 and new columns have been added with proper motions for a subset of objects.

StackObjectThinBadSkycells
Description: Contains the positional and photometric information for point-source photometry of stack detections. The information for all filters are joined into a single row, with metadata indicating if this stack object represents the primary detection. Due to overlaps in the stack tessellations, an object may appear in multiple stack images. The primary detection is the unique detection from the stack image that provides the best coverage with minimal projection stretching. All other detections of the object in that filter are secondary, regardless of their properties. The detection flagged as best is the primary detection if that detection has a psfQf value greater than 0.98; if that is not met, then any of the primary or secondary detections with the highest psfQf value is flagged as best.

Note that in the DR1 database, about 0.5% of the objects have more than one entry with primaryDetection=1. This may be fixed in a future modification of the DR2 database. Note also that as primaryDetection is entirely a geometric issue within a skycell, it is possible for an object (particularly if near the detection limit) to be undetected on the primary area within a skycell, but to appear on the overlapping non-primary area in an adjacent skycell. Such objects will not have any measurement which is flagged as a primaryDetection. bestDetection dimensionless TINYINT 1 255 Identifies if this row is the best detection. The entries in this column are currently corrupted in the DR2 database and should not be used. We recommend using the primaryDetection flag instead (although it also has shortcomings - see above). This is planned to be fixed in DR2.1. dvoRegionID dimensionless INT 4 -1 Internal DVO region identifier. processingVersion dimensionless TINYINT 1 NA Data release version. gippDetectID dimensionless BIGINT 8 NA IPP internal detection identifier. gstackDetectID dimensionless BIGINT 8 NA Unique stack detection identifier. gstackImageID dimensionless BIGINT 8 NA Unique stack identifier for g filter detection. gra degrees FLOAT 8 -999 Right ascension from g filter stack detection. gdec degrees FLOAT 8 -999 Declination from g filter stack detection. graErr arcsec REAL 4 -999 Right ascension error from g filter stack detection. gdecErr arcsec REAL 4 -999 Declination error from g filter stack detection. gEpoch days FLOAT 8 -999 Modified Julian Date of the mean epoch of images contributing to the the g-band stack (equinox J2000). gPSFMag AB magnitudes REAL 4 -999 PSF magnitude from g filter stack detection. gPSFMagErr AB magnitudes REAL 4 -999 Error in PSF magnitude from g filter stack detection. gApMag AB magnitudes REAL 4 -999 Aperture magnitude from g filter stack detection. gApMagErr AB magnitudes REAL 4 -999 Error in aperture magnitude from g filter stack detection. gKronMag AB magnitudes REAL 4 -999 Kron (1980) magnitude from g filter stack detection. gKronMagErr AB magnitudes REAL 4 -999 Error in Kron (1980) magnitude from g filter stack detection. ginfoFlag dimensionless BIGINT 8 0 Information flag bitmask indicating details of the g filter stack photometry.
