Instrument Availability and Target Accessibility: 2006A

The tables below indicate the current best estimates of instrument availability and corresponding target (RA, dec) accessibility for 2006A. 

The anticipated arrival of NIFS and TEXES at Gemini North, and NICI and Flamingos-2 at Gemini South, means that the instrument ports on both telescopes will be overfilled. Instrument swaps will be required and therefore not all instruments will be available for the entire semester. The defined RA ranges combined possible instrument exchanges with best-guess schedules. Where possible we have tried to provide the least restrictions to applicants and thus it is possible that some targets or entire programs might not be feasible when the final queue and schedule are assembled at ITAC.

Typically several observations or programs are rejected at the ITAC each semester because of target accessibility so please read carefully the following notes:
