Notes. Exp.t. is the exposure time in seconds; Sat.Eff.Mag. the satellite effective magnitude (for a contaminating satellite with V = 6 moving at 25°min−1); S/N is the measured signal-to-noise ratio; the S II and N II columns list the flux ratio, and Proportion is the ratio relative to the non-contaminated case.
