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 both the PS1 DR1 and DR2 data releases 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.

MeanObjectBadSkycells

Description: Contains the mean photometric information for objects based on the single epoch data, calculated as described in Magnier et al (2013). To be included in this table, an object must be bright enough to have been detected at least once in an individual exposure. PSF, Kron (1980), and aperture magnitudes and statistics are listed for all filters. References: Kron, R. G. 1980, ApJS, 43, 305; Magnier, E.

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.

primaryDetectiondimensionlessTINYINT1255Identifies if this row is the primary stack detection. 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.
bestDetectiondimensionlessTINYINT1255Identifies 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.
