OBSCAT data extracted 09/16/24

This page contains data for all observations (CAL + GO + GTO + DDT + TOO + CCT).

For each proposal cycle (AO stands for Announcement of Opportunity), there's a table showing, for each instrumet/grating combination, the number of obsids, the percentage of total obsids, the exposure time for those observations, and the percentage of the total time. The first column shows the AO number.

A plot of percentages by proposal number, vs. AO
