This notebook calculates/provides the positions and orientations of the IAS theodolite-total-station/autocolimator for initial alignment and positioning of the optical elements of the L1 Power Recycling Cavity, i.e. PRM, PR2 and PR3.
Notes and Changes:
The PR2 positional alignment solution calculated in E1200797-v6, had calculated the distance for the Total Station to the PR2 HR face, but we are measuring the distance to the AR face. Corrected this in E1200797-v7, and in this (-v4) update to E1200802.
