These two tables, taken together, imply that for a 500nm dichroic short-wave cutoff (with respect to a 400nm cutoff), there would be a 0.06 mag sensitivity loss at zenith, and a sensitivity gain at higher airmasses. A 600nm dichroic short-wave cutoff (with respect to a 500nm cutoff) loses an additional 0.12 mags sensitivity at zenith and doesn' | These two tables, taken together, imply that for a 500nm dichroic short-wave cutoff (with respect to a 400nm cutoff), there would be a 0.06 mag sensitivity loss at zenith, and a sensitivity gain at higher airmasses.
