Effective bandpasses used for the Legacy Surveys. The DECaLS, BASS and MzLS effective filter throughputs for the entire system are shown as solid (black), dashed (blue) and dotted–dashed (red) curves, respectively. These include the transmission of the atmosphere (at a median airmass of 1.1 for BASS and MzLS and of 1.4 for DECaLS), the reflectivity and obscuration of the primary mirror, the corrector transmission, and the quantum efficiency of the CCDs. The transmission data are archived on the Legacy Surveys’ website at http://legacysurvey.org/dr6/description/ (BASS gr and MzLS z) and http://legacysurvey.org/dr7/description/ (DECaLS grz).
