[Clas12_software] jcsg DC wire geometry in COATJAVA

[Mac Mestayer]

Hello Mikhail;

All of those values should come from the data-base,
and yes, we think they are all correct.

Hi Veronique,

I noticed in development version of COATJAVA the cell size called in:

Wire(int isuper, int ilayer, int iwire)
common-tools/clas-jcsg/src/main/java/org/jlab/detector/geant4/v2/DCGeant4Factory.java

dbref.cellthickness(isuper)=3.0 cm for all superlayers.

what are our cell thicknesses in the three superlayers?

Are midgaps in region 1,2 and 3 really these:
midgap(R1)= 2.50000172211009
midgap(R2)= 7.16074290360292
midgap(R3)= 2.49999999199041

How wire-distance is defined? Is it half-distance between two sense wires? 
Are the values below correct:
dbref.wpdist(isuper)=0.386160010000001,0.404219918000016,0.621906300000034,0.658596599999859,0.935140375500009,0.977981847999946
  cm?

Are theta mins correct:
dbref.thmin(isuper)=4.691432670569861,4.492809503848394,4.755235949489458,4.71702275655627,4.331440060891255,4.3317039097997245
  deg.?

Are distances to the first wire:
dbref.dist2tgt(ireg)=228.121068657577,351.968436599628,489.218708220582 
cm?

Thanks,
             Mikhail.
