GISMO run #5 (March 2012): installation of GIOSMO at its final and permanent position
Staffing of the test run
- GSFC: J. Staguhn, D. Fixsen, A. Kovacs, S. Maher, E. Sharp,
- IRAM: S. Leclercq, IRAM Granada staff
Test run schedule: 02.03. - 12.03.2012

GISMO does not appear with an explicit project number because the idea is to take up to 20 hours of the telescope time on the heterodyne pool (project 440-11). The decision for the time slots allocated to GISMO will be taken in real time (few to several hours in advance) through discussion between the GISMO team and the pool manager, based on observiong pool constraints (e.g. LST) and weather conditions.

GISMO final version
Same 8x16 pixels as 2nd to 4th runs, working at 2mm (the –3dB window is 140-162 GHz), with an individual pixel size = 0.9 Fλ.
Same special features from previous runs: 2 motorized neutral density filters, controllable shutter, automated observing procedures usable via a dedicated GUI (see observer's manual), (CRUSH) reduction package
- New updates: cold baffle, final position in the receiver cabin with corresponding warm optics.
