Section 3.1.2: masks of the very bright regions where the sub-pixel effect in the CO foreground templates prevent them to be used for cosmology or astrophysics analysis
Those masks are provided in the PLA.
The difference between the downgraded of the CO simulated map at Nside=128 and at Nside=2048 provides the level of the bias introduced by the downgraded CO template at each bolometer. Residual frequency maps have been computed using this information projected for each bolometer multiplied by the CO bandpass coefficient computed by SRoll. The table displays the mamps of the ratio of the variance inside each pixel at nside=128 in logarithmic scale between the CO frequency residual map and the noise level estimated from the End-to-end simulations. This bias is well determined and specific masks adapted to each scientific analysis can be computed from these ratio maps. It can also be noted that very few pixels have been biasesd at the level of the noise nearby the galactic center.
The table also gives the sky fraction masked by thresholding (100, 10, 1 %) the rms of the CO bandpass correction at Nside=2048 inside the pixel at Nside=128 referred to the rms of the noise at Nside=2048 inside the pixel at Nside=128.
