"Usage Statistics for the f/48 Camera"
by W. Hack

Abstract excerpted from the report:

This report details some analysis done to determine which filters and formats
were more heavily used for both science (by GOs and GTOs) and calibration 
activities. Of the 645 external images taken with the f/48 camera since 
launch, there were 245 taken by GOs and GTOs comprising roughly 40% of the 
total. In general, the calibraiton images have mirrored the science images
closely with only a couple of minor exceptions. These statistics should help
to determine the future calibration activities for the f/48 camera given its
high background features and turn-on problems.
