In a milestone statement distributed moments ago by the GPI Pre-delivery Acceptance Review Committee, Chair Stephen Goodsell announced that GPI is now clear for shipment from the University of California Santa Cruz to Gemini South in Chile.The Committee’s final report is slated for release on July 26th, but a statement sumarizing the results of the review is available now - GPI Review Committee: Final Day Statement 41 KB

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.
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.
Gemini Observatory is pleased to announce the release of the Gemini Instrument Feasibility Studies Request for Proposals (RfP).

Figure 1. Stellar Kinematic Maps of M60-UCD1 showing clear rotation and a dispersion peak. Panels a and b show the measured radial velocities (bulk motions towards & away from us) and velocity dispersions (random motions) of the stars in M60-UCD1 with typical errors of 6 km/s. Black contours show isophotes in the K band stellar continuum.
Example bias images are available for the following instrument/detector combinations:
UPDATE Sep 17 @ 4:00pm - the Gemini North Observing Database is back online. Please file a Help Desk ticket if you encounter any problems.
UPDATE Sep 17 @ 8:30am - the new hardware has been installed and we are working with the vendor to resolve network issues. We are hopeful that the GN ODB will be back online later today.
UPDATE Sep 16 @ 8:15am - work is ongoing, and we are still offline. Will post an update when we have more details.
The current version of the GMOS Mask Making software (GMMPS) is v0.4.1, released in 2014-08-27 for Linux and Mac OS X. This is an interim version to provide support for the new Hamamatsu detectors in GMOS-S. It is not yet fully backwards compatible (see below).
!! VERY IMPORTANT NOTE for GMOS-S users, concerning the Hamamatsu detector upgrade -- PLEASE READ !!
