Hi Sarah, Thanks for this very interesting pager. I think you have defined the alt dk jack correctly - the two angle groups are separated by 90 deg. Under 90 deg rotation a uniform monopole effect switches from T->Q to T->-Q. Therefore a uniform monopole cancels under 90 deg coaddition and doubles in the jack. For B2 and Keck2012 we had no jack to test for uniform monopole. Now we do and it appears to pass. I am not sure I see what you mean? Looking at B(pure) apmap and flicking between B2, Keck2012 and Keck2013 the most striking thing is that the pattern for Keck2013 looks rather blank in the left half. Looking at the 1/varmap there seems no reason to expect that...
