I think the figure (3b) is important to show that we are getting
weak lensing results out of the data, and so needs to be in the proposal.
I agree that the caption and text should emphasize that the
N_gal metric is preliminary and that we are exploring with more
sophisticated metrics for mass.
My personal preference would be to measure something more closely
tied to cluster mass. Turns out that observed 4.5 micron *flux*
(yes flux - negative k-correction plus passive evo. that fits cluster
data compensates quite nicely for luminosity distance)
is likely quite good for this purpose. But since that obviously can't
be done for all the clusters (at least not in the next few hours!)
don't mess with what is a surprisingly good looking
figure. We'll be looking more closely at cluster G, I promise!
Thanks Piero for the dust-free evidence in Alessandro's paper - I'd
forgotten that.
