HET Beginning-Trimester Report
First Period of 2003
December 1 - March 30

This report is composed of five sections:
Instrument Status

In this section we will discuss the status of each instrument and any limitation to configurations that occurred during the period.

The Rho ring engineering will bring the telescope down for about 3 weeks in January or February.


Expected Observing Conditions

The image quality of the HET has been improving each period. Here is a histogram from last period.

For comparison here is the image quality for the winter period of 2002

We expect to have similar overheads to last period:

Instrument Avg Overhead (min)
LRS 16.5
HRS 10.3


Observing Programs Status

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, and will give the CCD shutter open hours, overhead per visit, 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.


Institution Status

This is how each institution has allocated its time by priority.

Time Allocation by Institution (hours)
Institution Priority 0 Priority 1 Priority 2Priority 3 Priority 4
PSU 11.500 (10%) 25.200 (23%) 37.700 (34%) 36.500 (33%) 0.000

Priorities

The following are the high priority targets for the rest of the period for each institution:

UT02-2
RankProgram Constraints
1 UT02-3-012, GJ864 HRS, 3 tracks, Vsky > 20.0, EE50 < 3.0
2 UT02-3-003 HRS TOO SN2002JG, Vsky > 21.0 ,EE50 < 3.0
3 UT03-1-003 Synoptic HRS targets, Vsky > 20.3 ,EE50 < 2.0

PSU02-2
RankProgramConstraints
1 PSU02-2-050 HRS, 1 long visits on 1 possible dates, Vsky > 18.0, EE50 < 4.0
2 PSU03-1-009 HRS, many consecutive visits, Vsky > 20.0, EE50 < 3.0

STA02-2
RankProgramConstraints
1 STA03-1-001 LRS, 1 visit west track, Vsky > 21.0, EE50 < 2.0

MUN02-2
RankProgramConstraints
1 MUN02-3-001 LRS, Vsky > 21.0 , EE50 < 2.0

G02-2
RankProgramConstraints
1 G02-3-001 LRS, Synoptic target every 4-6 days for entire trimester, Vsky > 18.5 , EE50 < 4.0



The following is a histogram of the current HET queue. There is a lack of targets at the beginning of the night. The large number of priority 1 targets at 7.5 and 12 hours are UT MOS targets and none MOS g3 program: UT03-1-009, UT03-1-010, and UT03-1-008.
