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
Quasar feedback measured
Example bias images are available for the following instrument/detector combinations:
UPDATE Sep 16 @ 8:15am - work is ongoing, and we are still offline. Will post an update when we have more details.
The Gemini North observing database will be offline September 11-15 while we perform network infrastructure maintenance. During this time the following services will be unavailable:
- Phase I Tool guide star probability queries
- Observing Tool synchronizations and file transfers (Gemini North programs only)
- Observing Tool non-sidereal target queries (Gemini North programs only)
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 !!
Figure 1. Part of MACS J0416-2403 seen by GSAOI. The average angular resolution is about 80 milliarcseconds, the full field-of-view of the data released is nearly twice as large as shown here.
The latest version of the Gemini MOS Mask Preparation Software (GMMPS 0.4.1) is now available. Please see the GMMPS web page for more information and download links.
Calibrations for GNIRS consist of the following measurements.
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.
