Tucker et al. use 3.1-9.2 cm data from the balloon-borne BAM
(Balloon-borne Anisotropy Measurement) experiment to constrain CMBR
The FWHM of the beam, assumed to be gaussian, is
. The zero-lag window function of the two-beam experiment is
The first column in the window function file
is , which runs from
2 to 600. The second column is .
The quoted bandtemperature values are from Tucker et al., with 20% added
in quadrature to their statistical 1 error bars to account for the
BAM 1 calibration uncertainty.
