WFPC2 Technical Instrument Report 97-05:
Results of the WFPC2 SM-2 Lyman-Alpha Throughput Check
-O'Dea, Baggett, and Gonzaga
The WFPC2 throughput at wavelengths near 1200 Angstroms was monitored over the period 27-Feb-97 to 05-May-97. The far UV throughput was not significantly affected by the February 1997 servicing mission. Any change is less than the roughly 20% measurement uncertainty.
