Chap 37. Equ 37.1 params : Julian day, Longitude, Latitude, Radius

Calculate Pluto heliocentric ecliptical coordinates for given julian day. This function is accurate to within 0.07" in longitude, 0.02" in latitude and 0.000006 AU in radius. Note: This function is not valid outside the period of 1885-2099. Longitude and Latitude are in radians, radius in AU.

Specified by:

compute in interface PosFunc

Parameters:

calcDate - Computation date, as Julian day

eclipticPos - The rect coords of ecliptic pos, as a result
