This complex of web pages contains proposal statistics derived from data extracted from the OBSCAT. There are three cases considered:

• All observations (CAL+GO+GTO+DDT+TOO+CCT)
• No-CAL observations (GO+GTO+DDT+TOO+CCT)
• GO & GTO observations (GO+GTO+CCT)
• GO & GTO observations (GO+GTO+CCT incl. unobserved)

Note the data were extracted from the obscat on the date given at the top of the html page.

The statistics quoted here are for completed observations, and those in the short-term schedule as of the date indicated. This specifically excludes those with status canceled, unobserved, or untriggered. Presumably older AO programs are essentially complete, but the latest one is still very much in progress.

There are also plots of the percentage of proposals and exposure time spent in each instrument/grating combination.

In Jan 2019, Dick added CCTs to the statistics.
