PIIC data reduction
Beam maps new analysis
This new analysis of the beam maps extends what was done during the re-commissioning weeks (see the daily reports) Remeber that Box C of Ar2 is noisy and therefore mostof its KIDs are rejected, including the reference KID KC016. Therefore I am using KID KB013 as reference. Hence this same KID has been used as pointing KID during the observations. All pointing offsets were refereed to this KID. All maps are cenetred on this KID, although it is off-axis, and therefore all maps are slightly shifted (one-two 2mm beams) with respect to the geometrical/optical center of the f.o.v.
