| 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 140-162GHz (FWHM), pixels are spaced by '''13.75"''', the telescope HPBW is '''16.7"'''. The sensitivity is '''16 mJy sqrt(sec)''' per beam. The field-of-view is 1.8'x3.7'. In the standard observing mode, data are taken while the telescope follows Lissajous curves 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. The 2mm spectral range provides a unique terrestrial window enabling ground-based observations of the earliest active dusty galaxies in the universe and thereby allowing a better constraint on the star formation rate in these objects. |

Observations
How to observe
The Quick GISMO guide for dummies 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.
Pointing Sources
Plots for Pointing Sources can be accessed within the IRAM network. These data are provided ONLY to help in the planning of observations, in particular to select pointing and focus sources at the IRAM 30-m telescope. They should not be used for any other purpose.
Data reduction
GISMO data are reduced using CRUSH (Comprehensive Reduction Utility for SHARC2 - and more).
4th GISMO pool (October/November 2013)
The 4th GISMO pool will take place from the 22nd of October to the 5th of November 2013. Observations will be carried from a dedicated pool account (I. Hermelo will provide login information).
