Made reasonable beams. More of the central peak needed to be masked out. At ell of a few 100 only about 45 dB of variation between the main beam and the rest of the map can be reconstructed. The lowest values of the final maps is about 10^-6, maximum of the final map is 2.5×10^-2.

For these maps 5 deg in radius was masked out by setting the main beam to the value of the first unmasked pixels. This is a 10 deg diameter mask.

Andrea Z submitted simulation jobs yesterday evening - expecting execution in next day or two.

prior estimate of the CMB is not used - so text should reflect this point.

Make an additional offline document: there are plans to host a repository of PICO supplemental information (not just systematics) that would be available to the Decadal committee members.
