### FILE="Main.annotation"
## Copyright: Public domain.
## Filename: INTERPRETIVE_CONSTANTS.agc
## Purpose: A section of Luminary revision 163.
## It is part of the reconstructed source code for the first
## (unflown) release of the flight software for the Lunar
## Module's (LM) Apollo Guidance Computer (AGC) for Apollo 14.
## The code has been recreated from a reconstructed copy of
## Luminary 173, as well as Luminary memos 157 amd 158.
## It has been adapted such that the resulting bugger words
## exactly match those specified for Luminary 163 in NASA
## drawing 2021152N, which gives relatively high confidence
## that the reconstruction is correct.
## Reference: pp. 1091-1092
