Saskatoon 1995

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

The window functions were provided by B. Netterfield. There are three files,the two with NCP cap window function (c1 &c2) and one with the NCP ring window function. The first column in each window function file is $\ell$, which runs from 2 to 699. The last nine columns in the first cap file are the zero-lag $W_\ell$'s for the 3, 4, ..., 11 point chops. The last eight columns in the second cap file are the zero-lag $W_\ell$'s for the 12, 13, ..., 19 point chops. The last four columns in the ring file are the zero-lag $W_\ell$'s for the 3, 4, 5, and 6 point chops.

The quoted bandtemperature values are computed for a flat bandpower spectrum. They are from Netterfield et al., 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.
