... The 30apr15 data had not signal in beam 6b (the switch for the filter was broken) so beam 6 data from this set was discarded. ... Beam 0 was sampled more often than the others to get a better measure of the pointing offsets. ... Page 4: Pointing error (all beams) . Page 5: Pointing error (beam0). beam0 mean offsets will increase the rms of all beams. ... Compute the change in the pointing error if the alfa rotation error was off by -5 to +5 degrees in .1 degree steps. ... pointing errors: . ...
