Abstract

The MANIFEST Metrology Toolkit for GMT is set of in-house software tools to assist in the concept development and demonstration of the MANIFEST Metrology System. The Metrology Toolkit forms part of the ongoing MANIFEST pre- Concept Design Study conducted throughout 2019. The Metrology System is an essential component to provide precise location measurements of Starbugs over the focal-plane and relay this information to the positioning system. The goal of the Metrology System is to provide a positional measurement better than 30 microns (0.03 arcsecs) over a field-plate diameter of 1.2 m. The Metrology Toolkit is intended to be flexible to verify different implementations of the Metrology System.
