Ephem | ||
| Description: | This library is intended to provide the user with various ephemeris-generating routines, particularly in the calculation of planetary, solar, and lunar positions, and in the estimation of eclipse parameters. Most of the routines used may be found in Duffet-Smith (see the bibliography), although the iterative solution for Kepler's equation is found on pages 85-87 of the AE Roy reference, and none of the routines claim to be speedy or efficient -- mostly due to repeated calculations of positions with no saving of previous results. They have been tested against the examples provided in the sources and match with a reasonable amount of error (probably due to round-off in the examples). Planetary longitudes have been checked against the Menzel and Duffet-Smith sources at random, and are within a degree. A level of familiarity with astronomy and orbital mechanics is assumed. | |
