The Exoplanet Transit Ephemeris Service provides a user-friendly
interface where you can generate ephemerides and visible
transit times of exoplanets, accurate within one minute. Click the
links to the
left to learn more about its usage and how the underlying
calculations are done.
This service is based on the transit prediction service
(formerly transitsearch.org) developed by
Dr. Greg Laughlin (UC Santa Cruz). The algorithms used here differ
slightly from those used by Dr. Laughlin, and, combined with differences
in some input data, generated ephemerides may differ. A
short discussion of the differences can be found on the How Ephemerides are
Computed page.
May 21 2010: New Features: Ephemerides can now also be generated
using known transit midpoints and transit durations!
