#========================================================================================= # OSIRIS Shutter Calibration Parameteres #========================================================================================= # # 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 # # Transfer function of shutter blade: # # d = d0 + L(sin(th0) + sin(n*deg_per_stripe + thZ - th0)) # #pt=5.54 pt=5.14 L=100.0 d0=54.22 th0=3.77 thZ=1.83 deg_per_stripe=0.05
