Band Power Spectra and Parameters estimated from cleaned CMB maps

G. Rocha, 2018 October 31st


We report here the Band Power Spectra and parameters estimated for the component separation methods applied to Simulated data. For each method we estimate the full sky band power spectra with Xfaster, propagate to parameters with a Gaussian correlated Likelihood, and sample parameters with CosmoMC, marginalizing over tailored foreground residual templates. In addition we consider a hybrid likelihood: BFlike (pixel based likelihood) at low-l and XFlike (Xfaster likelihood) at high-l.

We compare the Bandpowers and residuals for SEVEM maps for Foreground Models 90, 91 and 92.


Band Power Spectra

SEVEM

Models 90, 91 and 92 - 155Ghz

Band Powers (BP) and uncertainties for SEVEM maps simulated considering the following foreground models: 90,91 and 92 (first panel).
Also shown are the residuals of the estimated BP and the input spectra used to simulate the input maps (second panel).
The BP was estimated with XFpipe.

BB bandpowers for 155Ghz - Models: 90, 91, 92 - lmax=300 and 1000

BB bandpowers for the 155GHz clean sevem map for foreground models 90, 91 and 92.
Note that the mask used for model 90 is not apodized while both masks for models 91 and 92 are apodized
Next we will replace by the BP estimated for the apodized mask and/or full-sky.
