As of 2012 Jan 21, the Pan-STARRS1 \(3\pi\) Survey has observed the3/4 of the sky visible from Hawaii with a minimum of 2 and mean of 7.6
observations in 5 filters, \(g_{\rm P1},r_{\rm P1},i_{\rm P1},z_{\rm P1},y_{\rm P1}\). Now at the end of the second
year of the mission, we are in a position to make an initial public
release of a portion of this unprecedented dataset.
This article describes the PS1 Photometric Ladder, Release 12.01
This is the first of a series of data releases to be generated as the
survey coverage increases and the data analysis improves. The
Photometric Ladder has rungs every hour in RA and at 4 intervals in
declination. We will release updates with increased area coverage
(more rungs) from the latest dataset until the PS1 survey and the
final re-reduction are completed. The currently released catalog
presents photometry of \(\sim 1000\) objects per square degree in the
rungs of the ladder. Saturation occurs at \(g_{\rm P1}, r_{\rm P1}, i_{\rm P1} \sim 13.5; z_{\rm P1} \sim 13.0;\) and \(y_{\rm P1} \sim 12.0\). Photometry is provided for
stars down to \(g_{\rm P1}, r_{\rm P1}, i_{\rm P1} \sim 19.1\) in the AB system.
This data release depends on the rigid `Ubercal' photometric
calibration using only the photometric nights, with systematic
uncertainties of (8.0, 7.0, 9.0, 10.7, 12.4) millimags in \((g_{\rm P1},r_{\rm P1},i_{\rm P1},z_{\rm P1},y_{\rm P1})\).
Areas covered only with lower quality nights are also included, and
have been tied to the Ubercal solution via relative photometry;
photometric accuracy of the non-photometric regions is lower and
should be used with caution.
