The PanSTARRS-1 (PS1) data processing pipeline generates catalogs of objects detected in the images. Each object may have measurements from one or more filters, and each filter may have measurements at one or more epochs. Objects may also be detected in stacked images that combine multiple epochs to produce deeper detection limits. All the detection information (positions, magnitudes, morphological information, flags, etc.) is stored in the PS1 databases, which will be the starting point for most science using PS1 data.
