CALLHORIZONS - a Python Interface to JPL HORIZONS
Overview
This module provides a convenient python interface to the JPL HORIZONS system by directly accessing and parsing the http website. Ephemerides can be obtained through get_ephemerides, orbital elements through get_elements. Function export2pyephem provides a convenient interface to the PyEphem module that allows for ephemerides calculations on your machine.
Installation
The easiest way is to install the module using pip:
pip install callhorizons
For other ways, see the documentation.
Documentation
The CALLHORIZONS documentation is available at http://mommermi.github.io/callhorizons/readme.html
Examples
print RA and DEC of asteroid 433 Eros from Mauna Kea for two discrete dates:
import callhorizons eros = callhorizons.query('Eros') eros.set_discreteepochs([2457446.177083, 2457446.182343]) eros.get_ephemerides(568) print eros['RA'], eros['DEC']
