The PS1 camera surveyed the sky using 5 filtersg, r, i, z, and y. The effective wavelengths (and spectral resolutions) of these 5 filters are 481 nm (R = 3.5), 617 nm (R = 4.4), 752 nm (R = 5.8), 866 nm (R = 8.3), and 962 nm (R = 11.6), respectively. Please refer to Table 1 in 4 in Tonry et al. (2012) for bandpass details. Schlafly et al. (2012) for further detailsprovides updated zeropoints in Table 1.
