it is part of the time accounting used to balance partner usage). Any time used between the hours of nautical sunset and sunrise to obtain baseline calibrations will not be explicitly charged to the program but will be charged to the partner country whose NTAC recommended time (i.e. Note that all calibrations, including baseline arcs, flats, spectral response standards and Nod & Shuffle Darks must be included in the Phase II science program.īaseline calibration data may be shared between programs and will be distributed to the users as part of their dataset.

If additional calibrations are deemed necessary by applicants, for example to achieve a precision beyond that achievable via the baseline set, then these must be included explicitly as part of the Phase I proposal and Phase II science program. The required "Night Basecal Time" per observation is automatically calculated by the Phase I Tool (PIT). Since 2017B the time required for nighttime baseline calibrations has to be included in the "Total Time" requested during Phase I. The baseline calibration set varies from instrument to instrument and from mode to mode. Baseline calibrations will be obtained for all observations, both queue and classical.įor all queue observations a set of standard calibrations (the "baseline calibrations"), shown in the tables below, will be taken by Gemini Staff to ensure the long-term utility of data in the archive. Flat-fielding is done with GCAL or on the sky during twilight. Wavelength calibration of GMOS is obtained using GCAL, the facility calibration unit.

Gemini are known for being energetic and quick-witted, and can blend into any social situation with ease. Have you been searching for your other half? Whether you're a Gemini or not, we think what you've been searching for is a book! Check out our book roundup for Twins' of all ages below to enjoy during Gemini Season (May 21 - June 20).
