[Rivet] Mailing list oops / 2D histos

[Andy Buckley]

Hi everyone,

Apologies if I've been unusually unresponsive to list emails recently. I
only just realised that my old Durham address had been bouncing, so I've
missed Rivet list emails for the last... actually, I don't know how
long. Since the start of September, I suspect. D'oh: I really thought I
had updated my list subscription to use a valid email address.

Anyway, apologies for the unintentional silence. I've heard via covert
channels that there's been discussion about 2D histos in Rivet... yeah,
if we'd had time to get YODA into action 1+ years ago we could have
avoided this. A pity that we didn't get user feedback about it being
needed: we definitely don't want to force people to look elsewhere.

At any rate, ROOT 2D histos can be used within Rivet and the
binEdges(...) functions can be used to do the autobooking for 1D histos.
We don't have any autobooking hooks for 2D histos yet, but I can put
them in for Leif's 2D histos in LWH -- and they will then be ready for
swap-over to YODA when that's usable. I've said that a lot, but there is
not so much more work needed: I would personally like to have a clear
run at that in the next couple of months so if others can pick up the
slack in the analysis development and core Rivet maintenance it will
happen faster.

Cheers,
Andy
