Some preliminary scan parameters discussed in the "Imager" telecon 28/08/2017.

In particular Kris plotted some hitcount maps and polarisation angle maps for the following configuration

• alpha = 22
• beta = 73
• T_precession = 11.751 hours
• T_spin = 121 s

The following illustrates the general scan strategy employed. This is the case for CORE and LiteBIRD too. scan_params.pdf
