Five filters (g, r, i, z, y),are used for PanSTARRS1 (PS1) exposures.  This section describes each filter and its characteristics.

Pan-STARRS is primarily sensitive to visible light, though observations extend slightly into the infrared passbands. Each camera included an identical set of 5 to 6 optical filters that can be remotely positioned in front of the focal plane.

The searches for asteroids and potentially hazardous objects may use a wide filter w ("g+r+i") that covers most of the visible waveband from 0.5 to 0.8 microns. This filter provides maximum sensitivity for detecting solar system objects. Surveys for stars and galaxies are much more valuable when they include color information, so Pan-STARRS will include standard photometric g-, r-, i-, and z-band filters, as used in the Sloan Digital Sky Survey. The excellent near-infrared response of the Pan-STARRS detectors means that we can also make use of a y-band filter (1.0 microns). All magnitiudes are quoted on the AB system.
