October 13th, 2021

Gemini will be releasing a new version of the Observing Tool (2021B.1.1.2) on Thursday, October 14, which includes several improvements, most notably support for the updated Horizons non-sidereal target database API.

The Gemini Observing Databases will be offline briefly on Thursday as each site is updated, during which time OT synchronizations and file transfers will be unavailable.

DRAGONS v3.0 Released!

October 13th, 2021

A new version of DRAGONS has been released.  This version offers improvements and fixes to the imaging support.  New in this version is support for GMOS longslit spectroscopy for quicklook purposes.  This new spectroscopy support is not approved for science quality reduction, but can be use for "quicklook" inspection of new data.   A quicklook reduction is intended to check the overall quality of the data, such as confirming the presence of the target(s) and whether the expected S/N has been achieved.
