This release of the throughput curves uses the "triple-silver" (3Ag) coatings for the mirrors, with as-measured values for the mirror reflectivity and witness sample tests of the filter throughputs. Lens throughputs (plus coatings) are as-measured.

The default detector QE curve is for the "joint minimum" -- aka, a hypothetical detector that is the worst of ITL and E2V at each wavelength.

All of the throughput curves here include an average (over time) loss estimate -- at some points in time such as just after cleaning the throughput will be slightly higher and at some points it will be slightly lower. The average is used to provide an estimate for the average depth for the entire survey.
