[Frost] Missing EPIC bank in g9a DSTs?

[Stuart Fegan]

Hi Franz,

That would make sense in theory, but here's a counter-example; linpol 
run number 55699 (1.3 GeV) it only exists in v2 and the file on /mss has 
no EPIC bank, although it does in my thesis skim version

Like I say, this may just be a few runs I was unlucky enough to take as 
my first choice, I'll only know for sure if/when I cache everything and 
redo the skim.  I was just hoping to just pull a few raw data files down 
to my laptop and prototype the skims I'm trying locally while I get the 
archaic version of rootbeer I have installed on CUE to play nice with 
the version of ROOT all my GlueX work currently depends on :-)

I'll keep everyone updated if this looks like becoming an actual problem 
and not a possibly imagined one.

Cheers,

Stuart
