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.
PS1 has specialized nomenclature.

Detection | Catalog data from a single exposure for a single detected astrophysical source. |
Object | An astrophysical source with one or more associated detections. |
Stack | Image constructed from all useful exposures overlapping a single sky cell. |

Put one or more images or figures at the top of this column. Novices may simply "Insert" an "Image" here. Experts should create first go to the "Media Repository" page and "Create" a new "PS1 image information" page for the new image. The image information page provide a mechanism for capturing metadata and including alternate versions of the figure.
Include an infobox below the picture. Summarize key facts in the infobox. The infobox helps users quickly assess the content of the article.
