For this file, the data scaled to the laserwire lens focal length is shown as well as the model the fitting program will use -> ie two different M2 models and their combined projection into the lab vertical. | ||||||||||||||||||||

> > | It should be noted, that this would appear to not be the best M2 data. Although care was taken, even greater care will need to be taken for the best possible data. Particular care should be taken to ensure the same relative capture block size to the laser beam as much as possible. | ||||||||||||||||||||
