2019 Bandpowers, Likelihood Code

Bandpowers and Map

Bandcenters, bandpowers, and bandpower errors for plotting are provided in a text file.

Bandpowers and uncertainties are given in [L_b(L_b + 1)]2 /2/pi units. Each row is one ell-bin. 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 Planck 2015 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).

The included map is a minimum-variance estimated convergence, mean-field subtracted and analytic-response corrected, in real space and in Fourier space. Please note that the simulation response correction is not applied. The map is in azimuthal equal-area projection centered at (RA, dec) = (0, -59.0) with 1 arcminute pixel size. Please contact Kimmy Wu (wlwu_at_kicp_uchicago_dot_edu) for questions regarding the generation and use of these data products.

Likelihood Code

We provide files in a zipped file that can be added to the Jul19 version of CosmoMC to interface with the SPTpol 500d CMB lensing bandpowers introduced above. 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 for running CMB lensing-only and CMB lensing + external data are provided as well. A simple README file provides details on where to place these files within a working CosmoMC environement. No recompilation of CosmoMC is required, as this likelihood uses a generic Gaussian likelihood structure existing within CosmoMC.

If you have any questions regarding the use of this likelihood, please contact Federico Bianchini (fbianchini_at_unimelb_dot_edu_dot_au).
