Table of Constants
The following table contains the constants needed to convert a local
datum to WGS84. This is the equivalent of entering a user-entered
datum in SETUP. Datums marked with "*" are defined in the unit.
When entering these constants, remember that
∆
a is displayed on the
screens as “DELTA A”,
∆
f x 10
4
is “DELTA f * 10000”, and so on.
