## South Pole TelescopeThese files contain one-dimensional azimuthally quadrature-averaged, Fourier-domain beam functions for South Pole Telescope (SPT) observations during the 2008 season for the 150 GHz and 220 GHz bands, produced for the first SPT data release in December 2011. The one-dimensional averages were computed from the Fourier transforms of the two-dimensional real-space beams. For details on the beam estimation procedure, see the documentation for those files. The one-dimensional, Fourier-domain beam profiles are normalized to 1 at multipole moment l=800. Estimates of 7 contributions to the beam uncertainty are included in additional columns. Brief descriptions of each source of uncertainty and the manner in which it is estimated follow.
A complete description of the observations, data processing, calibration, instrument response, and mapmaking process for this data release is in Schaffer et al. 2011, ApJ, 743, 90. |
