Gutiérrez et al. use 10 and 15 GHz data from the ground-based Tenerife experiment, in conjunction with diffuse foreground galactic 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
is , which runs from 2 to
130. The second column is .
The quoted bandtemperature values are from Gutiérrez et al., with 10% added
in quadrature to their statistical 1 error bars to account for the
Tenerife 1 calibration uncertainty.
