SwephFlag class

Flag bits for flag parameter in various methods The flag bits are defined in such a way that iflag = 0 delivers what one usually wants:

  • the default ephemeris (SWISS EPHEMERIS) is used,
  • apparent geocentric positions referring to the true equinox of date are returned. If not only coordinates, but also speed values are required, use flag = SEFLG_SPEED.

Constants

SEFLG_BARYCTR → const SwephFlag
barycentric position
SEFLG_CENTER_BODY → const SwephFlag
calculate position of center of body (COB) of planet, not barycenter of its system
SEFLG_DPSIDEPS_1980 → const SwephFlag
reproduce JPL Horizons 1962 - today to 0.002 arcsec.
SEFLG_EQUATORIAL → const SwephFlag
equatorial positions are wanted
SEFLG_HELCTR → const SwephFlag
heliocentric position
SEFLG_ICRS → const SwephFlag
ICRS (DE406 reference frame;
SEFLG_J2000 → const SwephFlag
no precession, i.e. give J2000 equinox
SEFLG_JPLEPH → const SwephFlag
use JPL ephemeris
SEFLG_JPLHOR → const SwephFlag
SEFLG_JPLHOR_APPROX → const SwephFlag
approximate JPL Horizons 1962 - today
SEFLG_MOSEPH → const SwephFlag
use Moshier ephemeris
