Comparison of P4 and P3 sky variation estimates. Left panel displays the global variations, estimated from the standard deviation of sky measurements at different areas (variable “DSKY” in P4 and “SKY1” in P3; the symbol colors are the same as in the previous figure). Right panel the local variation, estimated from the median scatter of sky values in local measurement areas (variable “RMS” in P4 and “SSKY1” in P3).
