Number counts of all detected sources measured from the Legacy Surveys DR6 and DR7 data releases compared with source counts from the PS1 survey. The DR7 number counts are measured in an ≈20.4 deg2 region centered on (R.A., decl.) = (243.°311, 9.°387). The DR6 number counts are measured in a ≈3.3 deg2 region centered on (245.°55, 43.°27). All the data shown are for sources detected at signal-to-noise ratios ≥5, and the PS1 sources are required to be detected in at least two of the grz bands in order to exclude spurious sources.
