The Pan-STARRS1 survey is collecting multi-epoch, multi-color observations of the sky north of declination −30° to unprecedented depths. These data are being photometrically and astrometrically calibrated and will serve as a reference for many other purposes. In this paper, we present our determination of the Pan-STARRS1 photometric system: gP1, rP1, iP1, zP1, yP1, and wP1. The Pan-STARRS1 photometric system is fundamentally based on the Hubble Space Telescope Calspec spectrophotometric observations, which in turn are fundamentally based on models of white dwarf atmospheres. We define the Pan-STARRS1 magnitude system and describe in detail our measurement of the system passbands, including both the instrumental sensitivity and atmospheric transmission functions. By-products, including transformations to other photometric systems, Galactic extinction, and stellar locus, are also provided. We close with a discussion of remaining systematic errors.

UPDATED NEARBY GALAXY CATALOG (2013, background): “It is clear that massive optical sky surveys like the Pan-STARRS (Tonry et al. 2012) and deeper “blind” HI surveys of the northern and southern sky will increase this number up to 1000 and over.”
PHOTOMETRIC CALIBRATION OF THE FIRST 1.5 YEARS OF THE PAN-STARRS1 SURVEY (2012, methodology): “This assumption is violated in the yP1 band, where there are strong water absorption features in the atmospheric extinction (see §4 and Tonry et al. (2012)).”
A LARGE CATALOG OF ACCURATE DISTANCES TO MOLECULAR CLOUDS FROM PS1 PHOTOMETRY (2014, methodology): “The photometric calibration is based on Tonry et al. (2012) and Schlafly et al.

Photometric redshifts for the SDSS Data Release 12 (2016, background): “A better camera and telescope can reduce photometric errors (Ivezic et al. 2008; Tonry et al. 2012), while a large selection of filters (Wolf et al. 2003), or filters designed specifically for photometric redshift estimation (Budavári et al. 2001) can remove degeneracies.”
THE PAN-STARRS1 DISTANT z > 5.6 QUASAR SURVEY: MORE THAN 100 QUASARS WITHIN THE FIRST GYR OF THE UNIVERSE (2016, background): “Given the width of the yP1 band of ∼ 800 Å (Tonry et al. 2012), Si iv + O iv] would contribute less than ∼ 10% of the flux in the broad band.”
