QMAP Data Products at LAMBDA

The design and performance of the instrument and results from the first flight are presented in Devlin et al. (1998).

The calibration and pointing are discussed and results from the second flight are presented in Herbig et al. (1998).

The mapmaking process and power spectrum extraction and combined results from both flights are presented in de Oliveira-Costa et al. (1998).

Raw Maps	In these sky maps, each row corresponds to a pixel on the sky. The five columns are x, y, z, T and sigma, where (x,y,z) is a unit vector in the direction of the pixel in equatorial coordinates, T is the measured temperature fluctuation and sigma is the rms noise. T and sigma are in units of micro-Kelvin.	6 files ~200 KB each
Wiener-filtered Maps	Since some pixels are much noisier than others and there are noise correlations between pixels, Wiener filtered maps are more useful than the raw ones for visual inspection. The pixels are in the same order as for the raw maps.	6 files ~69 KB each
