Retrieve and manipulate Jpl Horizons Ephemerides.
Project description
The eph package provides some useful classes to retrieve and manipulate ephemerides.
Basic Usage
import eph
req = eph.JPLReq() # create the request
req.read('defaults.cfg', 'jplparams') # read parameters from file
req.set({'COMMAND': '399', 'START_TIME': '2017-01-01', 'STOP_TIME': '2017-12-31'}) # set parameters from dictionary
res = req.request() # perform the request obtaining a response from jpl
eph = res.ephemeris # extract the ephemeris from the response
print(eph) # print dataThe content of defaults.cfg can be something like this (see ftp://ssd.jpl.nasa.gov/pub/ssd/horizons_batch_example.long for a complete description of JPL parameters)
