[Clas12_verystrange] [EXTERNAL] Re: Lambda from skim 14 - RG-A pass 1

[Matthew Nicol]

These do look great Will. I have managed to recreate them using very
similar cuts and running over all the skim14 data (Pass1), analysing
directly from the hipo files. It seems where I was skimming the files,
saving as a TTree and then reading it, I had some sort of coding issue, I
am investigating what this is now.
