Dicker et al. (JBIAC-large-angle) and Harrison et al. (JBIAC-small-angle)
use 33 GHz data from the ground-based Jodrell Bank-IAC interferometer
experiment on Tenerife, in conjunction with foreground contamination data,
to constrain CMBR anisotropy.

Dicker et al. and Harrison et al. provide analytic fits to their zero-lag
window functions (note that the normalization in eq. (6) of Dicker et al.
should be 0.0677, not 0.677). The large-angle zero-lag window function
fit is

and the small-angle zero-lag window function fit is

The first column in the window function
file
is , which runs from 2 to 350. The
second column is the large-angle and the third column is the
small-angle .

large-angle | 90 | 105.9 | 109.5 | 129 | 0.175 |

small-angle | 190 | 206.8 | 208.5 | 227 | 0.0922 |

The quoted bandtemperature values are from Dicker et al. and Harrison et al.,
with 6.6% added in quadrature to their statistical 1 error bars to
account for the calibration uncertainty. They were computed assuming a flat
bandpower spectrum.
