In this section we will discuss the status of each instrument and any limitation to configurations that occurred during the period.
Here is a histogram from the last period.
For comparison here is the image quality for the period last year.
We expect to do a few tenths better than last year; about as good as the previous period.
We expect to have a similar overhead to last period. The following overhead statistics include slew, setup, readout and refocus between exposures (if there are multiple exposures per visit). In the summary page for each program the average setup time is calculated. The table below gives the average setup time for each instrument PER VISIT and the average and maximum PROPOSED science exposures and visit lengths.
| Instrument | Avg Overhead per Actual Visit(min) | Avg Overhead per Requested Visit(min) | Median Overhead per Requested Visit(min) | Avg Exposure (sec) | Median Exposure (sec) | Max Exposure (sec) | Avg Visit (sec) | Median Visit (sec) | Max Visit (sec) |
|---|---|---|---|---|---|---|---|---|---|
| LRS | 14.2 | 17.4 (from last period) | 15.9 (from last period) | 668.8 | 600 | 1800 | 1078.3 | 600 | 4800 |
| HRS | 10.6 | 13.3 (from last period) | 11.5 (from last period) | 860.5 | 900 | 2520 | 1166.3 | 900 | 9420 |
| MRS | 12.6 | 10.4 (from last period) | 10.4 (from last period) | 850 | 750 | 1050 | 1700.0 | 1500 | 2100 |
NOTE: AS OF 2003-3 THE SETUP TIME FOR AN ATTEMPTED MRS OR HRS TARGET IS CAPPED AT 15 MINUTES.
The overhead statistics can be shortened by multiple setups (each one counted as a separate visit) while on the same target as is the case for planet search programs. The overhead statistics can be lengthened by having multiple tracks that add up to a single htopx visit as can happen for very long tracks where each attempt might only yield a half visit.
A way to improve the overhead accumulated for programs with long exposure times is to add double the above overhead to the requested visit length and make sure that time is shorter than the actual track length. This avoids the RA having to split requested visits between several different tracks.
The following links give the summary for each institution and its programs.
The resulting table will give (for each program) the total number of targets
in the queue and the number completed, the CCD shutter open
hours, average overhead for that program, and the TAC allocated time.
This usually will be the best
metric for judging completeness but there are times when a PI will tell
us that a target is "done" before the total number of visits is complete.
This is how each institution has allocated its time by priority.

The following histogram shows some of the extrema in observing conditions: good seeing dark time, bright time and bad seeing dark time. There will be a problem later in the trimester with a lack of bright time targets.
