Queue Summary : Semester 2003A Gemini North and South

The queues shown in the tables below summarise the programs that have been awarded time on Gemini North and South. Jump directly to the queue for:

• Gemini North
• Gemini South

The queue is constructed by the International TAC from the ranked list of proposals of each National TAC using the merging sequence and is divided into four scientific ranking bands (SRBs). Joint proposals (submitted to more than one NTAC for joint support) were combined by the ITAC, are shown in the table as a single entry and are executed as such. Several proposals have multiple occurrences as they were sub-divided by the relevant NTAC; each component is executed separately. 

Within each band, all proposals are assumed to have equal scientific merit and have been sorted by PI name for convenience. The choice of which observation within which program to execute next depends on the match to current observing conditions, the balance of each partner's usage and other factors such as future accessibility, whether a program has been started etc. (see a detailed discussion in Puxley 1997; Gemini Preprint #19). The aim is to exhaust band 1 (highest ranked) programs before moving onto band 2 and so on. An observation in band 1 that does not require the best conditions will nevertheless be executed in preference to a band 2 observation even if the latter is a better match. Thus the likelihood of execution decreases from band 1 through to band 4. Bands 1 through 3 aim to fill the nominal time available (excluding weather loss). Programs in band 4 overfill the queue and provide further flexibility with respect to weather conditions and foreseen or unforeseen problems.

In routine operation the intent is to update this page nightly. During shared-risks science use, this queue status page may only be updated after each observing block with a given instrument. 

Note that individual SRBs will not be in detailed balance with respect to partner shares. Aggregating over two or more bands generally provides an equitable distribution of queue loading (in hours, not in the number of proposals) once any classically-scheduled programs are taken into account. Additional flexibility is available when executing observations to balance the partner usage of time. The intent is to achieve balance over 2 or 3 semesters, not a single semester.

The columns in the table for Gemini North are:
Ref #: Gemini reference number (note that this is different from any internal National TAC reference number). Click on it to see the proposal abstract (when available).
PI: name of Principal Investigator. (If a joint proposal, the name of the primary contact for the entire program is listed).
Partner: partner or country to which time will be charged (US, UK, CA=Canada, AU=Australia, AR=Argentina, BR=Brazil, UH=University of Hawaii (host), GS=Gemini staff). If a joint proposal, all contributors are shown.
Title: the title of the program.
Instrument: name of the instrument(s).
Hours allocated: time allocated to the program (if a joint proposal, this is the total time for the program).
Execution status: current status of the program (e.g. awaiting Phase II preparation by PI, awaiting checking of Phase II science program by National Office or Gemini staff, active in the queue [and for GMOS only, awaiting MOS mask design], completed)
Data taken: the UT date on which data were taken [later this will include time used for each observation made]
Completion status: this shows an estimate of the fraction of allocated time that has been used. Note that this is a preliminary estimate and is only an indication of the completion state of the program. The completion state may not reflect the formal time accounting. Also note that some programs may be completed in less than the allocated time (e.g. if conditions were better than requested or if the request was overestimated). 

A list of the support staff (Gemini Contact Scientists and National Office staff) for each program is available.

The columns in the table for Gemini South are:
