This page provides data products associated with the multifrequency SPT-SZ power spectrum measurement described in Mocanu et al., 2019. The power spectra at 95, 150 and 220 GHz are presented over the angular multipole range 650 < ell < 3000.
If you have any questions regarding this data set or its use, please contact Tom Crawford (tcrawfor_at_kicp_dot_uchicago_dot_edu).

The file dl.txt contains nominal ell bin centers and bandpower values D_l = l(l+1)/2pi*C_l
in units of uK^2 for the multifrequency SPT-SZ data used in Mocanu et al. (2019).
The auto- and cross-frequency bandpowers are ordered as follows:
95x95, 95x150, 95x220, 150x150, 150x220, 220x220, with 47 ell-space
bins for each frequency combination (282 bandpowers in total).
The blocks in the associated covariance matrix in the unformatted
binary file cov are ordered similarly. The covariance matrix
has 282*282 elements and
includes contributions from noise, sample variance, and beam and calibration
uncertainties.
The bandpower window
functions are stored in the unformatted binary file wf,
which has 4651*282 total elements. Each of the 282 window functions is
defined from ell=0 to ell=4650 and is associated with the bandpower given
by the ordering above.
UPDATE 16NOV20: Replaced covariance matrix file with a copy
in which the beam and calibration elements were calculated using a
data model that includes foregrounds. (The original was the version
used in the linear fit in the paper, which was appropriate for
bandpowers in which a best-fit foreground model had been subtracted.)
