Milestone 6.3: Integrated performance specification ready

The integration of the initial Performance Specification document with the first version of the updated Science Case and the first version of the Handbook of Measurement Principles is a comprehensive Performance Specification covering the hardware and software elements of the new system, and showing how the science goals can be addressed.

The delivery of the first version of this integrated Performance Specification is Milestone 6.3. This document was produced in April 2012, but was not accepted by the EISCAT_3D Executive Board until November 2013. Thus Milestone 6.3 was reached in November 2013.
