The Goddard-IRAM Superconducting 2mm Observer (GISMO) is a bolometer camera for the IRAM 30m telescope. It has been build by Goddard Space Flight Center, in Greenbelt, Maryland under the lead of Johannes Staguhn. GISMO consists of '''8x16 pixels''' with super conducting transition edge sensors (TES). The TES are read out by time domain SQUID multiplexers built at the National Institute for Standards (NIST), in Boulder, Colorado. The nominal bandwidth is 140-162 GHz (FWHM), pixels are spaced by '''13.75"''', the telescope HPBW is '''16.7"'''. The sensitivity has improved relative to the April 2011 run to about '''10 mJy sqrt(sec)''' (cf. report below). The field-of-view is ''' 1.8'x3.7' '''. Two standard observing modes are offered, Lissajous curves and on-the-fly scans. Both work in total power, without switching the secondary. An automated pipeline merges the GISMO data with the telescope data streams to create FITS files which are automatically processed by the reduction software crush to create logs, pointing results, and a first quick view of the data. Typical overheads for single science targets on the sky are 60%. The relative flux stability is about 8% (cf. report below).

== Observing Runs ==



=== April 2013 - 3rd pool run ===



==== Pool projects and observers ====

 * Winter semester 2012 observations will be carried out as pooled observations from a dedicated pool account. M.Gonzalez will provide login information.

 * [[http://www.iram.fr/php/rel_sched/bgfiles/13/Bolopool-w12.html|List of accepted projects.]]

 * Progress of observations can be followed via the [[https://herapool.iram.es|pool data base]].

   * [[https://herapool.iram.es/GISMO/|external with slow updates]]



==== Observing scripts ====

 * GismoObservingScripts provides examples and explanations about how to start !PaKo in order to run the telescope with GISMO, and about total power maps using Lissajous and On-the-fly patterns. Observations using the wobbler will not be offered for this run. The old page GismoHowToObserve is obsolete.
