The Coude is part of the overall Telescope Mount Assembly (WBS 1.0) and consists of two WBS packages, the Coude Rotator Structure (WBS 1.1.3) and the Coude Rotator Drive System (WBS 1.1.4). The original fabrication of the Telescope Mount Assembly was done by Ingersoll Machine Tools.
The Coudé Rotator Structure is the large, single-level steel assembly that rotates about an azimuth axis inside of the Pier. It is comprised of the structural elements that support Coudé instruments and optical benches underneath the mount, the bearings that allow for rotation, and also the flooring system.
The Coudé rotator drive system is the assembly of drives, encoders and controllers that allow the coudé rotator to track and de-rotate the light feed from the mount, align slits of spectrographs, and to slew to different positions during normal telescope operations.
