git fetch [name1]

WARNINGS:

• Be aware of the magnitude of mis-alignemnts. The track finding/fitting may not work properly if too large of shifts or rotations are made. For example in global X and Y we expect shifts of O(0.01) mm and X, Y rotations of O(0.001) radians, Z rotaion of O(0.0001) radians.
• Make sure to change the paths in condor scripts to your own paths.
