Earth-Moon distance implied by a length of day (angular momentum conserved)

Usage

moon_distance_from_lod(lod_h, kind = "solar", L_total = NULL)

lod_h: Length of day in hours (numeric vector, > 0; 24 today), of the type set by kind. Required (no default).
kind: Type of day given in lod_h (character, passed to earth_omega): "solar" (mean solar day) or "sidereal" (one rotation relative to the stars). Default="solar".
L_total: Total angular momentum of the Earth-Moon system in kg m^2/s (numeric, > 0), assumed to be conserved. NULL uses the present-day value (computed from today's Earth-Moon distance and length of day). Default=NULL.
