 A ROC will transfer GEM data from a CAEN V1495 to the host DAQ computer.  At the local institution there will only be one element of the Qweak tracking software.  Once the ROC is writing data to a CODA file from the V1495 we will need to write software which will take the raw data and create a data structure for tracking.  The data structure for tracking, in the case of R1, will contain the distance of the elastic scattering event from the beam pipe center (<math>R</math>) and <math>\phi</math> representing the local polar angle in which <math>\phi=0</math> at the center of the detector.
