SEVEM results on model 90.00, no delensing

We have produced cleaned frequency maps at 62, 75, 90, 108, 155 and 186 GHz for the simple 90.00 model (homogeneous foregrounds over the sky) produced by Clem using template fitting. We have considered the simulation number 0000, with no delensing.

The different frequency maps can be used to obtain directly the auto-spectrum or for cross-correlation between them.
The noise, synchrotron and dust components have also been propagated through the pipeline. We have also propagated the tensor component provided with the simulations.
We understand that this component should be rescaled by a factor of 0.3 (in cls) to obtain r=0.003, which is what has been ingested in the simulations.

The following figures show the power spectrum for the cleaned map at 155 GHz as well as the synchrotron, dust, noise and 0.3*tensor components propagated through the pipeline for the full-sky (to avoid the E-B leakage problem). Therefore, this is the expected level of each of the components in the cleaned maps. The same figure is also shown for the cross-correlation between the cleaned 90 and 186 GHz frequency channels. A small level of correlated noise is expected between any pair of cleaned channels, since some common templates are used to clean the maps.

One can see that foregrounds residuals are below the CMB tensor component for a large range of multipoles.
The cleaned maps are available at NERSC at /project/projectdirs/pico/barreiro/SEVEM/
