Planpos[] is an array with many different types of coordinates and related variables:

Geocentric (mostly) coordinates:

• 1 = gcl = Apparent geocentric ecliptic longitude
• 2 = gcb = Apparent geocentric ecliptic latitude
• 3 = r = True heliocentric distance
• 4 = delta = Apparent geocentric distance
• 5 = ra = Apparent geocentric R.A.
• 6 = dec = Apparent geocentric declination
• 7 = tau = Geocentric light time in days
• 8 = hh = Apparent geocentric hour angle
• 9 = az = Apparent geocentric azimuth
• 10 = alt = Apparent geocentric altitude
• 11 = elon = Apparent TOPOCENTRIC elongation, using topocentric altitude and correcting for refraction
• 12 = diam = Apparent geocentric apparent diameter

Magnitude, phase, parallax:

• 13 = magn = Apparent visual magnitude
• 14 = k = Illuminated fraction
• 15 = pa = Phase angle
• 16 = parang = Topocentric parallactic angle
• 17 = hp = Horizontal parallax

Topocentric (mostly) coordinates:

• 21 = topl = Apparent topocentric ecliptic longitude
• 22 = topb = Apparent topocentric ecliptic latitude
• 23 = delta0 = True geocentric distance
• 24 = topdelta = Apparent topocentric distance
• 25 = topra = Apparent topocentric R.A.
• 26 = topdec = Apparent topocentric declination
• 28 = tophh = Apparent topocentric hour angle
• 29 = topaz = Apparent topocentric azimuth
• 30 = topalt = Apparent topocentric altitude
• 31 = topalt + refract = Apparent topocentric altitude, corrected for refraction
• 32 = topdiam = Apparent topocentric apparent diameter

Heliocentric coordinates:

• 33 = l = Apparent heliocentric ecliptic longitude
• 34 = b = Apparent heliocentric ecliptic latitude
• 35 = r = Apparent heliocentric distance
• 36 = hcl00 = True heliocentric ecliptic longitude, FK5
• 37 = hcb00 = True heliocentric ecliptic latitude, FK5
• 38 = hcr00 = True heliocentric distance

Other variables:

• 39 = pl = Planet for which data were computed
• 40 = jde = JDE for the instance of calculation
• 41 = l0+pi = True geocentric ecliptic longitude for the Sun, in FK5
• 42 = -b0 = True geocentric ecliptic latitude for the Sun, in FK5
• 43 = r0 = True geocentric distance for the Sun
• 44 = lst = Local APPARENT siderial time (radians)
• 45 = agst = Greenwich APPARENT siderial time (radians)
• 46 = t0 * 10.d0 = Apparent dynamical time in Julian Centuries since 2000.0

• 50 = eps0 = Mean obliquity of the ecliptic, without nutation

More geocentric coordinates:

• 51 = sun_gcl,b = Apparent geocentric longitude of the Sun (variable was treated as if pl.eq.3)
• 52 = sun_gcl,b = Apparent geocentric latitude of the Sun (variable was treated as if pl.eq.3)
• 61 = gcx = Apparent geocentric x
• 62 = gcy = Apparent geocentric y
