FOC Instrument Science Report #071 4/93 Update on the FOC f/96 Absolute Sensitivity by P.E. Hodge Abstract excerpted from the report: Observations of BPM 16274 were used to determine the absolute sensitivity of the FOC f/96 relay through nine medium-band filters ranging from F120M to F550M. The sensitivity appears to be a few percent lower than it was a year or two ago.
