 Overview 




We make available on this page data products related to the
cosmological parameters analysis of the SPT+Planck 2500 squaredegrees
lensing measurement presented in Simard et al. (2017), based on results presented in Omori et al. (2017). The lensing bandpowers used for the
cosmological analysis cover the lensing angular multipole range 50
<= L <= 1991; chains can be run within the CosmoMC infrastructure with
the likelihood files provided below.
If you have any questions regarding this data set or its use, please
contact Gabrielle Simard (simard_dot_gabrielle_at_gmail_dot_com).


 Bandpowers 




Bandcenters, bandpowers, and bandpower errors for plotting are provided in a text file
here.
Bandpowers and uncertainties are given in [L_b(L_b + 1)]^2 /2/pi
units. Each row is one ellbin. The columns are (1) bin number, (2)
L_min, (3) L_max, (4) center of bin, (5) estimated clpp bandpower, (6)
sigma on the estimated clpp bandpower, (7) lensing amplitude compared
to the base_plikHM_TT_lowTEB_lensing cosmology.
These bandpowers are foreground subtracted, where the lensing
foreground model has been taken from van Engelen et al. (2014)
(astroph/1310.7023). Note that the lensing bandpowers plotted in
Fig. 5 of Omori et al. (2017) are not foreground subtracted, whereas
the ones in Fig. 1 of Simard et al. (2017) are.


 Likelihood Code 




The attached directory can be added to the November 2016 version of
CosmoMC. The CosmoMC dataset contains the foreground template removed
lensing bandpowers, the corresponding lensing bandpowers covariance
matrix and the lensing linear corrections. The appropriate batch
files are provided as well. A simple README file provides details on
where to place these files within a working CosmoMC environnement. No
recompilation of CosmoMC is required, as this likelihood uses a
generic Gaussian likelihood structure existing within CosmoMC.
sptplanck_lenslike v1.1: December 7th, 2017. Initial version to be released with the arXiv submission.


 Chains 




The chains computed in the context of this analysis are available
here. The directory base.zip containts
chains in the LCDM model for the SPT+Planck lensing data only and in
combination with the Planck TT + lowP likelihoods. Each directory
base_X.zip contains chains in the LCDM model with the X parameter(s)
varied for the SPT+Planck lensing data in combination with the Planck
TT + lowP likelihoods.
The chains samples in the root.txt files contain the burnin phase;
the first 30% of the rows should be removed. The format of each row
in the root.txt files follows the habitual CosmoMC format, where the
first column corresponds to the weight, the second column to the
log(likelihood) and the following columns to the value of the primary
and derived parameters listed in the corresponding root.paramnames
file.
