This is an update of Calibration06072013 i.e. I use the internal parameters found on that day and just re-estimate the external parameters
using exp_name = 'GigE_mocap_update'

I'm using the internal parameters from 6/18/2013 because these estimates are better

UPDATE: 8/8/2014,'ve determined that the calibration for this day isn't very good, and I'm going to try to correct it
	-I'm using the .Pmat.cal and .rad files as initial conditions
