Field distortions

The plate scale of FLAMINGOS-2 ranges from 0.1792 arcsec / pixel on-axis to 0.1787 arcec / pixel at the outermost radius. Even though modest, these distortions must be taken into account when coadding sets of dithered images to avoid image degradation.

Background & Exposure times

Choosing suitable exposure times


FLAMINGOS-2 is a near-infrared imaging spectrograph at Gemini-South, offering observations in the 1.0-2.4 μm wavelength range in a 6.1 arcmin circular field of view. Currently, imaging and long-slit spectroscopy modes are offered, while the multi-object spectroscopy mode is awaiting its commissioning.

Gemini North in scheduled shutdown until August 25

Gemini North as of July 10 2017 is in a scheduled shutdown for dome shutter repair and instrument maintenance. The shutdown is planned to be completed by August 25 2017.

July 2017 Call for Proposals

Gemini North and South are accepting proposals for the Fast Turnaround (FT) program. Here, we give information specific to this proposal cycle. Please see the other FT pages - particularly the rules - for general information about the program. FT-specific proposal templates must now be used for all FT proposals; see the "PIT information" section below. The revised 2017B PIT must be used
