Introduction

Optical pointing is used to derive the antenna pointing solutions based on observations of stars. It is expected that there will be of the order of 5 optical pointing system available for the main array during commissioning or after maintenance at the OSF. Possibly the ACA antennas may all be equiped with optical pointing systems.

It is assumed that the reader is at least somewhat familiar with the ALMA Observing Tool (OT). If not please read at least Chapter 3 and 4 of the User Manual. The optical pointing functions described here are additional to the features described in that guide.
