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

I performed a scan using 36 detectors for a period of $4$ years using the same scanning strategy as Kris. The detectors are spread in 9 rows, each row having an ideal configuration (0, 90, 45, 135 degrees). Each row is separated by ~9' towards increasing beta. The map is then rescaled for 144 detectors. | I performed a scan using 36 detectors for a period of $4$ years using the same scanning strategy as Kris.

+ | I took as an example the Band #10 at 107.5 GHz. This has a beam of 7.91'. As a rule of thumb I took the number of samples along the scan direction as 4 per FWHM. This gives me a scan frequency of ~85Hz. | ||
