The figures on this page summarize the RA distributions for queue programs in the semesters 2006B, 2007A, and 2007B at Gemini North and South. Distributions of both the planned and executed observations are shown. Only science observations are included in the distributions. The distributions show the number of hours worth of observations at each RA. Programs that were withdrawn have been excluded from the distributions. Template observations for ToO programs are not included as these in general contain no RA information.

On each figure the approximate available time (number of hours) is shown, scaled to the fraction of the planned queue time that is included in each of the distributions shown on that figure. This is the absolute maximum number of hours that can be executed, without any loss to weather or technical problems, and no time for calibrations or engineering on the sky. While the science observations typically can be executed within an hour angle of +- 3hours, it is quite clear that in some cases the planned observations cannot realistically be executed within the available time. This is in particular the case for GN-2007A at RA=12-14h. This RA range includes both the North Galactic Pole and the HDF-N.

PIs with programs in band 3 and with flexibility in target selection are encouraged to use the information in these figures for selection of alternative targets at RAs in less demand from band 1 and 2. As for all target change requests, these need to be submitted for approval to the local Head of Science Operations, see the change request page for details.
