Tucker et al. use 90 GHz data from the ground-based White Dish experiment
at the South Pole to constrain CMBR anisotropy. Ratra et al. (1998)
summarize the experiment.
The FWHM of the beam, assumed to be gaussian, is
. The zero-lag window function of the two-beam Method I (see
Tucker et al. or Ratra et al. 1998) experiment is
The first column in the window function file
is , which runs from 2 to
2500. The second column is the White Dish Method I zero-lag .
The quoted bandtemperature values are from Ratra et al. (1998). They were
computed assuming a flat bandpower spectrum and, following Ganga et al.
(1997), account for the White Dish absolute calibration uncertainty of 30%.
Ratra et al. (1998, 1999) use the White Dish data to constrain
