GNIRS Temporarily Unavailable

Due to ongoing problems with its cold heads, GNIRS is about to be removed from the telescope and warmed up for closer inspection. We should know by Friday October 10th whether this intervention has been successful. The instrument will not be available for observations during this period, and NIRI will be installed on the GNIRS telescope port instead (see the 2014B telescope schedule: http://www.gemini.edu/sciops/metrics/gn2014Boverview.html).

GMOS-S Array (EEV)

This information refers to the EEV detectors at GMOS-S. These were removed in May 2014 and are no longer available. The Hamamatsu detectors were installed in June 2014. 

 

The GMOS South detector array consists of three 2048x4608 EEV chips arranged in a row. The table below gives a summary of the current detector/controller characteristics.

Calibration

Calibrations for GNIRS consist of the following measurements.

GMOS-S Gain and Read Noise Values

The table below gives gain/read-noise values for the current GMOS Hamamatsu CCDs measured in September 2014.

Note: GMOS South data obtained before May 19, 2014 should use the previous gain/read-noise values.
