Or noticed that the right arm pathl variable was empty.  I found that the
right arm VDC database did not have pathlength coefficents for the 
pathlength correction.  The left arm VDC database did and are the ones
determined for the Transversity experiment.  

It seems that the e'd experiment for the time-being elected to use the 
pathlength terms from the left HRS.  I am not sure how well that works, 
but we will try them to start with.  I checked the databases from the 
first SRC experiment and found that the coeffiecients between left and 
right arms were basically the same.  I added the pathlength coefficients
to 'db_R.vdc.dat' in the following directories:

As it turns out, we are not using the most recent optics matrix from 
3He(e,e'd) for the right arm.  For the left arm, we are.  I decided to 
not change the optics matrix for now, since I am not sure how much it
will change the target reconstruction.  It all depends on where the 
right arm matrix came from(?).
