"11.92 nm Distance calculated Bowditch constants
12.06 nm Distance calculated / my constants
12.04 nm Distance calculated / Frank's constants"
Just to clarify, I do not recommend any particular constants for Table 15.
The calculation underlying Table 15 is HIGHLY susceptible to variability in
terrestrial refraction. I would recommend doing this calculation with a range
of constants to get some feeling for the possible variation.
