[clas12_rgk] Fwd: Re: [EXTERNAL] Rg-K quality plots

[Annalisa D'Angelo]

Dear Volker
you are right the quality plots were produced for RGA, but they require 
pass1 to be completed. I think he sent me the slides he used to show the 
potential of the available code used when RG-K will have pass1 done.

We can only use the timelines which were run over 4 reference calibrated 
runs.
I still need to understand the meaning of some of the variables...though.
