Programmatic Requirements for Gemini Instrumentation Development

 

 

3 Introduction

 

Section 19.4.2 of the document “Programmatic Requirements for Gemini Instrumentation Development” states the requirements for the Service and Calibration Manual.

 

In short, it needs to provide the information necessary to guide service and maintenance of the instrument. To this end, a major part of the document is devoted to assembly and disassembly procedures, and to inspection, realignment, and calibration procedures. Photographs are used where appropriate to show procedures, and histories and results are included as indicators of normal operating parameters and as diagnostic tools.
