Transformation (Projection) Matrices Between SEI/SUS Coordinates (ISI to SUS)

Document #:

LIGO-T1100617-v4

Document type:

T - Technical notes

Abstract:

This document describes the implementation of the transforms between the ISI and the SUS coordinates. It outlines the math necessary to transform between SEI and SUS coordinates using matrices and a little bit of SolidWorks knowledge from systems.
