Queue Summary : Semester 2004B 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: band 1, 2, 3, 4 (and previous semester band 1 rollover: 04A)
• Gemini South: band 1, 2, 3, 4 (and previous semester band 1 rollover: 04A)

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 for this page to represent the current status. Currently the Execution Status (an active link) is updated from the Observing Database every ~4 hr; the Completion Status may only be updated after each observing block with a given instrument. The timestamp of last update for each instrument is given at the bottom of the page.

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.

There is an NGO support staff queue schedule for Gemini North and South

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). Programs identified e.g. [r05A] were assigned rollover status by the ITAC and will be carried over into the specified semester if not completed in this semester. Programs carried forward from previous semester(s) are linked at the top of this page.
Execution status: click on this hyperlink to see the current status of each observation in the program. 
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). 

The assigned support staff (Gemini Contact Scientists and National Office staff) for each Gemini North ODB and Gemini South ODB program are listed in the configurable 'snapshots' of the Observing Database (ODB).

The columns in the table for Gemini South 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, CH=Chile (host), AR=Argentina, BR=Brazil, GS=Gemini staff). If a joint proposal, all contributors are shown.
Title: the title of the program.
Instrument: name of the instrument(s).
