- M1M3 bending modes (07/2014)
- data in ASCII format. 1st two columns are x and y coordinates of the FEA nodes. Unit is meter. The coordinate system is the same as the LSST Optical Coordinate System (OCRS), i.e., x is along the elevation bearing; when telescope is pointed at horizon, y points up, and z points toward the sky. Col. 3 - 22 are first 20 M1M3 bending modes in meter. These are surface sag with 156 axial actuators. The piston-tip-tilt on the mirror surface has been kept. Details on how the bending modes are obtained can be found in Document-16390.
