Saskatoon 1994

Netterfield et al. (1995) use Ka band (centered on 30 GHz) and Q band (centered on 40 GHz) data from the ground-based Saskatoon 1994 experiment at Saskatoon to constrain CMBR anisotropy.

The window functions were provided by B. Netterfield. There are two files, one with the Ka window functions and one with the Q window functions. The first column in each window function file is $\ell$, which runs from 2 to 499. The next seven columns in each file are the zero-lag $W_\ell$'s for the 3, 4, ..., 9 point chops. Some of the $W_\ell$ values in these files are negative, due to numerical round-off errors. To deal with this, it suffices, for all practical purposes, to use $\vert W_\ell\vert$ instead of $W_\ell$ tabulated in these files.

The quoted bandtemperature values are computed for a flat bandpower spectrum. They are from Netterfield et al. (1997), corrected according to the caption of Figure 3 of Torbet et al. (to account for re-calibration and foreground contamination), with 11% added in quadrature to their statistical 1 $\sigma$ error bars to account for the 1 $\sigma$ calibration uncertainty.
