Director's Discretionary Time Summary : Semester 2011A GS

The data shown in the tables below summarise the programs that constitute the "Director's Discretionary Time" (DDT) on GS. DDT proposals are typically for time-critical observations which cannot wait for the normal proposal cycle (e.g. unexpected astronomical events) or for testing the feasibility of a technique or of a program. See the DDT web page for more information. DDT proposals may be submitted at any time by any astronomer world-wide.

In other respects - contact scientist support, Phase II definitions, Gemini Science Archive data distribution - DDT programs are similar to other Gemini queue programs.

This report is generated daily (see the bottom of the page for the current timestamp). The pages linked via Execution Status are updated approximately every 4 hours. Note that the completion fraction may change as the time accounting is adjusted during the quality assessment process.

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 (UH = University of Hawaii, GS=Gemini staff) or country (US, UK, CA, CL, AU, AR, BR) to which time will be charged. If a joint proposal, all contributors are shown.
Title The title of the science program.
Instrument Name of the instrument(s) required.
Hours Allocated Time allocated to the program (if a joint proposal, this is the total time for the program).
Execution Status Click on this hyperlink to see the current status of each observation in the program.
Data Taken The UT date(s) on which data were taken.
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 interactive 'snapshots' of the Observing Database (ODB).
