QMAP

Devlin et al. (QMAP I) and Herbig et al. (QMAP II) use Ka band (centered on 30 GHz) and Q band (centered on 40 GHz) data from the balloon-borne QMAP 1996 flights to constrain CMBR anisotropy.

The window function file were provided by L. Page. The first column in the window function file is $\ell$, which runs from 2 to 500. The next two columns are the QMAP I Ka and Q zero-lag $W_\ell$'s while the last three columns are the QMAP II Ka1, Ka2, and Q zero-lag $W_\ell$'s.

Table: QMAP zero-lag Window Function Parameters

	$\ell_{e^{-0.5}}$	$\ell_{\rm e}$	$\ell_{\rm m}$	$\ell_{e^{-0.5}}$	$\sqrt{I(W_\ell)}$
QMAP I Ka	56	92.0	107	159	0.996
QMAP I Q	43	83.7	88	146	0.996
QMAP II Ka1	60	91.1	122	165	0.996
QMAP II Ka2	141	145.2	184	224	0.997
QMAP II Q	76	125.4	148	228	0.997

The quoted bandtemperature values are computed for a flat bandpower spectrum. They are from Devlin et al. and Herbig et al., with the Ka results corrected to account for foreground contamination (following de Oliveira-Costa et al.), with 11%(12%) added in quadrature to their statistical 1 $\sigma$ error bars to account for the 1 $\sigma$ I Ka and II Q (I Q and II Ka) calibration uncertainty.
