Gemini Observatory invites its community to propose scientific investigations for the 2014B semester, 1 August 2014 - 31 January 2015.
The original GMOS-N detector array consisted of three 2048x4608 EEV chips arranged in a row. This array was replaced by e2v deep depletion devices in October 2011.
The table below gives a summary of the original EEV detector/controller characteristics.
Detector characteristics are given in this section. Note that the GMOS-South detectors will be upgraded for 14B. Note also that the telescope optics are now silver-coated, reducing the system throughput in the blue.

Wavelength Calibration Accuracy & Flexure
This page is focussed on the wavelength calibration accuracy and the IFS flexure compensation.
Extended Objects: Europa Observations
Europa, satellite of Jupiter was observed on November 18, 2013 from 08:42:16 (airmass=1.63) to 08:48:16 (airmass=1.64) under average seeing conditions (DIMM seeing~0.6-0.8) in K1 band, and direct mode (no coronagraph, no apodizer). Eleven data cubes with a true integration time of 8.73 s were processed by M. Perrin using the recipe listed below.
Recipy used to process Europa Data
GPI is a complex instrument and the performance is changing quickly with improvements in data reduction and the instrument wavefront sensor control loops. The performance has been broken down into the following areas:
Our understanding of performance and calibration is a work in progress; these pages will continue to be updated as more on sky calibrations are taken and analyzed.
