To open the Ephemeris Generator
screen, go to the Lists/Ephemeris/Ephemeris
menu. The Ephemeris
window will show up.
- Start and End
Dates. Enter the date from which you want the Ephemeris to
start and the date at which you would like Ephemeris to finish.
- Interval. This will set the
frequency at which ephemeris dates will be shown.
- Time Units. You can set the
time unit at which ephemeris will be incremented. This field can be
set to Minutes, Hours, Days, Weeks, Months, and Years.
- Coordinates Systems. You can
set the Coordinate System to Geocentric, Topocentric, Heliocentric,
and Galactic coordinates value.
- Coordinates. This option allows you to define how
results will be presented - in Ecliptic (longitude and latitude) or
Equatorial (RA and declination) coordinates.
- Zodiac. Use this field to
change the Zodiac from Tropical (default) to Sidereal. For all
possible Ayanamsa values, please see the Ayanamsa values list.
- True Node. If checked, the
True North Node will be calculated, if unchecked, then Mean Node will
be calculated instead. Please note that setting this field will
override default User Settings.
- Time Zone.
You can select the TimeZone name or set the time zone offset in
- Click the OK button. The
ephemeris data will be shown in the Ephemeris Table.
- The number of displayed rows (dates) will always be limited to 35
irrespective of time unit and step settings.
- Galactic coordinates system is based on the Galactic Center as
defined by Harlow Shapley. Precession is taken into consideration for
calculating longitude and latitude of the Galactic center.
- When using Galactic coordinates system, the Galactic Center assumed
to be a fixed point and so the speed calculations will be identical to
