Planning GMOS Observations

Gemini Observatory hosts substantial documentation and other resources for each instrument, and for planning observing programs. Observations with GMOS can be particularly challenging, in part because of the large number of available instrument configurations and observing modes. The following pages are particularly relevant to planning both science and calibration exposures with GMOS, and should be reviewed carefully:

GMOS users who are planning an observing program will benefit from considering the needs and requirements of the subsequent data reduction. Well planned observations will make data reduction and analysis a happier experience. This guide begins with a primer on the configurations and capabilities of the GMOS instruments:

The following chapter discusses cases where additional calibration exposures may be important for achieving the science goals of an observing program.

Finally, technical terms used in this guide are defined in the Glossary.
