We detail improvements to the PS1 SN photometry, astrometry, and calibration that reduce the systematic uncertainties in the PS1 SN Ia distances. We combine the subset of 279 PS1 SNe Ia (0.031 discovered by HST (Riess+, 2004) J/AJ/131/527 : UBVRI light curves of 44 type Ia supernovae (Jha+, 2006) J/AJ/131/1648 : Type Ia supernovae at high and low redshifts (Blondin+, 2006) J/ApJ/659/122 : Improved distances to type Ia supernovae (Jha+, 2007) J/ApJ/666/674 : ESSENCE supernova survey (Miknaitis+, 2007) J/AJ/136/2306 : SDSS-II Supernova survey, 2005 (Holtzman+, 2008) J/ApJ/700/331 : Light curves of type Ia supernovae (CfA3) (Hicken+, 2009) J/ApJ/700/1097 : Light curve parameters of SN Ia (Hicken+, 2009) J/ApJS/185/32 : First-year SDSS-II SN results (Kessler+, 2009) J/AJ/139/519 : Carnegie supernova project.
