MAT 1998

Miller et al. use D band (centered on 144 GHz) data from the ground-based MAT (Mobile Anisotropy Telescope) 1998 experiment on Cerro Toco, Chile, to constrain CMBR anisotropy.

The window function file were provided by E. Torbet. The first column is $\ell$, which runs from 2 to 1300 (although one $W_\ell$ is not computed to $\ell = 1300$). The next five columns are the combined D1 + D2 zero-lag $W_\ell$'s for groups 6, 7, ..., 10. Each group is a combination of various $n$-point chops of D1 and D2 data; see Miller et al. for details.

Table: MAT 1998 D1 + D2 zero-lag Window Function Parameters

	$\ell_{e^{-0.5}}$	$\ell_{\rm e}$	$\ell_{\rm m}$	$\ell_{e^{-0.5}}$	$\sqrt{I(W_\ell)}$
Group 6	96	128.8	122	153	0.998
Group 7	117	155.0	148	183	0.998
Group 8	185	248.4	260	302	0.999
Group 9	267	318.6	304	347	0.999
Group 10	334	415.0	365	446	0.999

The quoted bandtemperature values are computed for a flat bandpower spectrum. They are from Miller et al. with 8% added in quadrature to their statistical 1 $\sigma$ error bars to account for the 1 $\sigma$ calibration uncertainty.
