Data taken as part of instrument System Verification (SV) or for other engineering
purposes (including the Demonstration Science programs) and that are deemed to be of
scientific value 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 data packages are listed below. The table includes the instrument,
data package reference name, (astronomical) target name and a brief summary of the data. A
more complete description is contained within the data package itself. Click on the
hyperlinks to download the raw or processed data (generally the processing was taken to a
state that allowed quality assessment and therefore does not represent the best possible
reduction e.g. for scientific analysis) in several formats:
- A 'preview' version of the combined data (as jpeg or gif, if available)
- The processed, combined data (as gzipped fits file, which should saved to disk)
- The complete package (as gzipped tar file(s); these should be saved to disk for
unpacking)
The gzipped files may be saved to disk by using "shift+click" or
"right-click" plus choose "save" from your browser's menu.

This mosaic image of the Orion BN/KL region was obtained with
Gemini-North in preparations to test the spectroscopic mode of OSCIR
on the BN object itself. The sky background conditions had degraded
to a point where regular programs in the queue could not be executed.
Because the object came out so spectacularly, we decided to construct a
mosaic, which allowed to test chopping strategies on objects larger
than the OSCIR detector. The observations were also used to establish
the orientation of the OSCIR field for the QuickStart observing run.
The image can be compared with those published by Gezari et al.
