ACKNOWLEDGEMENT
This report was prepared under DSR Project 55-23870, sponsored by the Manned
Spacecraft Center of the National Aeronautics and Space Administration through
Contract NAS 9-4065.
The publicationof thisreport doesnotconsitute approval bythe National Aeronautics
and Space Administration of the findings or the conclusions contained therein. It is
published only for the exchange and stimulation of ideas.
Foreword
This document comprises all flowcharts completed by the date of publication for
Luminary ID programs, routines, and subroutines. (Reference Exhibit D, Paragraph
3.3, of M.I.T. Statement of Work, NAS 9-4065, period 1 January 1968 - 30 June
1970.)
Those flowchartsnot completed and notincluded withinthe currentedition are denoted
by an asterisk on the table of contents. As they become available, newly completed
flowcharts will be forwarded for, inclusion, with an updated contents and index.
The index to the present volume is an alphabetical listing of flag bits, subroutines,
and major entries. In addition to the flowchart and sheet number for each entry,
the index gives the flowchart and sheet number where each flag bit is set (S), cleared
(C or tested (T).
