Leitch et al. use 15 and 32 GHz data from the ground-based OVRO (Owens
Valley Radio Observatory) experiment in Owens Valley, in conjunction
with foreground contamination data, to constrain CMBR anisotropy.
The FWHM of the beam, assumed to be gaussian, is
. The zero-lag window function of the three-beam experiment is
The first column in the window function file
is , which runs from
2 to 4000. The second column is .
The quoted bandtemperature values are from Leitch et al., and include 4.3%
added in quadrature to the statistical 1 error bars to account for
the OVRO 1 calibration uncertainty.
