I have to admit that I don't, would have to look it up as well. It's what 
Markus Warsinsky told me was sensible to use in the context of the Atlas 
analysis.

Sherpa's new min bias model is definitely clever ;-), but its 
implementation isn't finished yet, at least not to an extent where I would 
trust it for the validation of an analysis.
I don't know yet how much time I will have during the weekend to work on 
this (none in theory), so if you haven't managed to do it during the 
weekend, I'll try to do it on Monday before the official tarball is out. 
Actually I just realise that it is currently not in the unvalidated 
library, but hey ... I consider it already validated anyway (it's the 
plots that Markus Warsinsky showed in the tuning meeting).

Cheers,
