#  The data is coded in tag = value format where
#
#  The tag has the format:
#     pt		    : Distance from home position to edge of CCD
#     L			    : Length of shutter arm [mm]
#     d0            : Distance from reference point to leading edge of shutter blade [mm]
#	  th0	        : Rotation angle of shutter arm in home position [deg]
#     thZ	        : Roration angle of shutter arm at zero position encoder location [deg]
#     deg_per_stripe: Number of degrees per shutter encoder stripe [deg]
#
#  The calibration values in this file originate from: the Calibration Report
#  RO-RIS-UPD-TN-W333-213
