I agree that we should use Hijing Ncoll values if available - it will be really quick to make new A, B fits if / when I get them - but I understand that it's far from trivial to extract them from Hijing. > One thing is the relative behaviour of the rMS in oir data.

Look at: http://lynx.uio.no/trine/brahms/mult/RMS_with_pp_AMPT_fullerrors.gif (syst.error bars included for AuAu points) and: http://lynx.uio.no/trine/brahms/mult/RMS_with_pp_reducedrange.gif and ...../RMS_with_pp_reducedrange2.gif (removed 1) uppermost and 2) two uppermost points in Eta for AuAu and pp distributions from RMS calculations, to explore the consequences of slightly different eta ranges - I think the latter picture is pushing the uncertainty.) The shift in pp RMS relative to the "centroid" for the AuAu RMS set is about 0.05. Interpolated to the same eta range as the AuAu data the pp RMS would be 2.38 +-0.05 ....
