Wollack et al. use Ka band (centered on 30 GHz) data from the ground-based
Saskatoon 1993 experiment at Saskatoon to constrain CMBR anisotropy.
The FWHM of the beam, assumed to be gaussian, is
. The zero-lag window function of the
stepped-scan, second harmonic lockin, three-beam experiment is
The first column in the window function file
is , which runs from
2 to 350. The second column is the zero-lag .
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 error bars to
account for the 1 calibration uncertainty.
