Abstract:

This is primarily an index entry in the DCC to collect links to initial alignment solutions. The provided links are to notebooks which calculate/provide the positions and orientations of the IAS theodolite-total-station/autocolimator for initial alignment and positioning of the primary optics. They also calculate/provide the pitch angles of the COC relative to the local horizontal. The alignment solutions (angles, positions/distances) caluclated in this notebook are to be inserted into each of the IAS alignment procedures.
Since there is one common Mathematica notebook used to calculate these alignment solutions, it is filed under this DCC entry. Occasionally specific variants are filed under the subsidiary DCC numbers, but the intent is to keep the most up-to-date version filed under this DCC entry.
