I for one was surprised to be reminded, clicking
through this pager,
that the effect of the arc vs RAdec projection is subdominant to relgain
deproj, but not to diffpoint deproj. Is that right?
I think so.
If so, and if you've been hoping we can avoid
relgain deproj, then why
haven't we been pushing the arc projection?
Well I think the thought was that for Kendrick+A/B+RA/Dec the residual E/B
leakage was low enough that it was subdominant to noise - so it didn't matter.
Although for B2 3yr I'm not sure that is still true. I think you also argued
that the simple mapping of scans to x-direction in the RA/Dec projection made
the 2d aps easier to interpret - although it's not like looking at those damn
plots seems to have taught us much recently ;-)
