Gemini GSAOI System Verification Data

Data taken as part of GSAOI System Verification (SV) are made public after an assessment period typically not longer than 2 months. You are encouraged to take these datasets and assess or use them yourself.

The available GSAOI data are listed below. The table includes the program reference IDs and titles, brief summaries of the data, examples of reduced data (only for some programs), and links to the observing logs and data in the Gemini Science Archive. Click on the hyperlinks to download the raw or PI-processed data (in some cases the processing was taken to a state that allowed quality assessment and therefore may not represent the best possible reduction, e.g. for scientific analysis.

The data sets are linked to GSA queries of the complete catalog, which return all raw data for the program. Calibrations can be searched using the instructions in the GSAOI page.

The GS-2012B-SV-499 programme contains data obtained during commissioning of the instrument, as well as of the AO system GeMS, which is being released to the community as it represents valuable scientific datasets. However, note that since those observations were taken for specific commissioning tasks, full (or optimal) calibration sets may not be available.

More information about a programme can be obtained through the Gemini Helpdesk.

GeMS commissioning with GMOS-S -- Not released through the GSA

Due to problems with the GSAOI filter wheel in March and May 2012, those two GeMS commissioning runs were conducted using GMOS-S in imaging mode, using the i_G0327 and z_G0328 filters. The instrument itself was NOT commissioned to be used with the AO system, so there are several issues with the image headers, including (but not limited to) the WCS solution and plate scale. Some of the data obtained are listed below, but are NOT available through the Gemini Science Archive due to the above mentioned header problems. For the same reason, the GEMINI.GMOS data reduction package is NOT likely to work "out of the box" with these datasets. Please contact the GMOS-S Instrument Team through  the Gemini Helpdesk if interested.
