Rob and Ariel,
I believe that the filter story for the other team is pretty simple: they
ended up using only one slightly different filter for restframe B (and maybe one
for restframe V) -- and I think had to use ordinary Cousins filters at telescopes
without the special filter. So this should be a managable task to clear up.
