pub const LTC_LUT_SIZE: usize = 64;Expand description
Edge of the square lookup table. 64 matches the resolution the parameterisation
was chosen for: finer buys little once sqrt(1 - cos) has spread the grazing
angles out, and the fit cost grows with the square.
In its own file because build.rs include!s it alongside the fitter, while
the lib compiles only this half.
