HI Rich, sorry I didn't have time to look at this yet. My expectation would be that an efficiency binner would have asymmetric errors, because of the constraint 0<=eff<=1.

I did find the code which does the efficiency calculation. It is

http://java.freehep.org/svn/repobrowser.svn?path=%2ffreehep% 2ftrunk%2fjaida%2ffreehep-jaida%2fsrc%2fmain%2fjava%2fhep%2f aida%2fref%2fdataset%2fbinner&revision=HEAD&name=fre ehep&bypassEmpty=true

EfficiencyBinner.java and
EfficiencyBinError.java

I believe the algorithm was swiped from HandyPak!
