|Detection||Catalog data for a single source from a single exposure.|
|Object||Catalog data for one or more associated detections.|
|OTA||Orthogonal Transfer Array. An OTA consists of an 8 x 8 array of 600 x 600 pixel CCD cells. The PS1 camera consists of 60 OTAs.|
Published Science Product System. This is the PS1 object database.
|Sky cell||One tile in the PS1 tessellation of the sky.|
|Stack image||Image constructed by combining all useful warp images that overlap a single sky cell. Sometimes simply referred to as a "stack".|
|Stack detection||Catalog data for a single source from a stack image.|
|Stack object||Catalog data for one or more associated stack detections.|
|Tessellation||The scheme used to cover the spherical sky with a regular pattern of rectangular images in a manner that leaves no gaps in coverage.|
|Warp image||Image constructed by resampling a single exposure onto a canonical sky cell projection. Sometimes simply referred to as a "warp".|
|Ubercal||The process that uses comparisons in flux measurements from overlapping exposures to improve the global calibration.|
