Class Method Details

.fetch(client, body, options = {}) ⇒ Object

Public: fetch an ephemeris table for a given body using the client

client - Tengai::Client body - a Tengai::Body instance whose ephemeris is needed options - A Hash of options for refining the ephemeris table

:start_time - The Time beginning of the ephemeris
:stop_time - The Time end of the ephemeris
:interval - The resolution of the table in minutes
