KHALDEA EphemerisTM core data is accurate within 0.3 arcsecond (three-tenths of a second arc) for all positions when compared to the best data generated by the Jet Propulsion Laboratory - the JPL DE406 and LE406. In the aspectarian, which is displayed below the ephemeris for the years 1900 to 2100, aspects and other timed data are accurate within one minute (on the clock).
