[vsnet-alert 10954] Exoplanet Transit Database

[Luboš Brát]

Dear collegues, observers of transiting exoplanets.

Let us introduce new tool for exoplanet transits observers. During year 2008, we have developed an Exoplanet Transit Database (ETD), where are collected all published transit observations. You can see the data both in table and in graphical output of relations: timings vs epoch, transit depth vs epoch, transit duration vs epoch. 

Besides this, there are two other main functions, especially for observers. Transit predictions and Data fitting procedure.
Transit predictions are available for all locations around the world, just type your longitude and latitude. For each object, transit timings for next year are available (with highlighted observable transits vs bellow horizont or during daylight). 

Data fitting procedure is automatic on-line application form, where observer can upload his photometric observation of transit event. The application will fit your data with model light curve and find out time of midtransit, depth and lenght of the transit. There is also possibility to publish your transit observation in TRESCA database (TRansiting ExoplanetS and CAndidates) and after revision directly in ETD.

Our database administrators are periodically checking for new transits both in literature and in on-line internet sources (TRESCA, AXA)and updates the ETD database. New transiting exoplanets published in literature are also included to ETD as soon possible after discovery.

Feel free to use all features of Exoplanet Transit Database and in case of  anny suggestions, please contact us.

And now the most important information: Exoplanet Transit Database can be found at
