Abstract

We report the results from the second flight of QMAP, an experiment to map the cosmic microwave background near the north celestial pole. We present maps of the sky at 31 and 42 GHz as well as a measurement of the angular power spectrum covering 40 ≲ l ≲ 200. Anisotropy is detected at ≳ 20 σ and is in agreement with previous results at these angular scales. We also report details of the data reduction and analysis techniques that were used for both flights of QMAP.
