 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.

 +Band #10 quotes a raw sensitivity of 46 muK/sqrt(Hz). To have a comparison with results for CORE I assumed a white noise of 40 muK/sqrt(Hz). These maps can be easily rescaled for the appropriate noise.
