Hi Michael,
I looked at the latest recrunch (v3_4_17), here you can find some plots
for the offsets (from what I saw, they are consistent with the previous
version v3_4_16):

http://einstein.unh.edu/~adrian/secondRecrunch/

In the last plot there I show the target distribution for left (blue) and
right (red) protons and the corresponding electrons in magenta and green
(I think this is what you asked for)... All elastic cuts were used for
this plot (so only events between -20 and +20 cm target vertex are shown).

Just for offset comparison, here are the plots for v3_4_16 presented last
week:

and the plots for the really old crunch presented the week before:

http://einstein.unh.edu/~adrian/beforeRecrunch/

I did not have the four-color target plot for these crunches, but all
the other offset plots are there...

Adrian
