QMAP

 
The photo on the left shows, from left to right Tom Herbig, Mark Devlin, Stu Bradley, Amber Miller, Lyman Page  and Barth Netterfield on the Palestine launch pad in front of Tiny Tim just before flight 1.
Not shown, though who played a major role, are Angelica de Oliveira-Costa  (Princeton and IAS)
and Max Tegmark  (at IAS). In addition,  Norm Jarosik built and designed the bi-phase telemetry system. Bill Vinje and Glen Monnelly worked on the HEMT radiometers. Chris Gabel and Andrea Wood worked on electronics. Jed Beach wrote most of the attitude control code.

The picture on the right shows the  map produced by the experiment. The hot and cold spots are
dominated by fluctuations in the CMB. The circular region in the middle was covered by the
SK experiment.

The QMAP experiment is finished and will not be flown again. The gondola and receiver are
being used in the MAT  experiment.

The initial results from QMAP are being submitted to Ap. J. in three letters:

• Devlin et al, where a detailed description of the design and performace of QMAP instrument is presented, as well as, results from the first flight. See also QMAP/Penn.
• Herbig et al , where details of the calibration and pointing analysis are presented, as well as, results from the second flight.
• de Oliveira-Costa et al, where details of the data analysis method (the mapmaking process and the power spectrum extraction) are presented, as well as, the combined results from both flights.

Details of the experiment and data reduction/analysis may be found on Tom Herbig's QMAP/INFO page. Additional information on mapmaking and power spectrum analysis can be found on Max Tegmark's CMB anisotropy analysis page.

Maps and covariance matrices can be found here at Max Tegmark's site.
