The table below summarizes the amount of time each program has
used.
Program is the observing run name, or the coversheet
identification. "public" is a special observation, where the data are
available to all users. These are generally standard star
observations. Other examples may include pointing models which are
not charge to any one and do not have any corresponding exposure time.
The value in the Obs, for observation time, is the total number
of hours of clock time including overhead used by the program.
The value in the Exp column, for exposure time, is the total
number of hours of open shutter time for that program.
Alloc is the allocation to the program by the TAC in hours.
Team simply lists the program team, with the subitting PI first.
This table simple summarizes the observing conditions per month.
Month is the year, month and starting day of the time considered.
Total represents the total number of hours of darkness, defined
as between -9 degree sunset to -9 degree sunrise, over the month.
OK gives the number of hours it was determined to be ok to open
the telescope. Reasons for closure may include weather or
engineering issues.
The FWHM lists the average seeing for the month.
Transparency lists the typical transparency for the telescope in
magnitudes as compared to a fiducial zeropoint. This may reflect
clouds or it may reflect other issues.
