Program Updates

We will use this space to announce changes to the website and to address questions received from the community. Updates will occur approximately once per week.

August 2022:

Objects fainter than K=11mag are not feasible (and not permitted) in Band 3 conditions.

March 2022:

Overheads

There have been adjustments in 2022B to better account for time required to observe telluric stars.

The default overheads in the Gemini PIT for telluric star observations is now 15 minutes per hour.

The other overheads are unchanged.

Observers must add additional overheads for science target acquisition and detector readout.

These additional overheads should be added to the exposure times requested.

The minimum time request (exposure time + science overheads+ basecal) for any IGRINS observation is 0.25 hours.

August 11, 2021: Overhead estimates need to be adjusted in 2022A to include time for science target acquisition and detector readout.

See 'Proposing and Phase II' for new instructions.
