3 Introduction

 

Section 19.4.3 of the document “Programmatic Requirements for Gemini Instrumentation Development” states the requirements for the Software Maintenance Manual.

 

This manual should describe the software at a sufficient level of detail so that a programmer familiar with the Gemini environment, but not initially familiar with the software, can maintain it properly. It should include:

·         Detailed written descriptions of all software systems and sub-systems.

·         Systems analyses.

·         Data flow diagrams.

·         Data dictionaries.

·         Structure charts.

·         Specifications.

·         Listings of all software including firmware (DSP code).
