INSTRUCTION: In the first step, just select an exoplanet and load data file with observation. Also select if data are in geocentric or heliocentric JD and specify, if brightness is given in MAG or FLUX. Both geocentric and heliocentric JD must be computed from COORDINATED UNIVERSAL TIME (UTC) with leap seconds included (common time in your PC / notebook).

Choose exoplanet
Data file with observation: Required 3 columns: JD, MAG, ERROR. Other columns are ignored. Columns must be separated by space or TAB.
JD format:	geocentric heliocentric (both based on UTC)
Brightness column:	in magnitudes in flux

Model light curve fitting procedure: O.Pejcha, 2008 (read description).
Database and web interface: L. Brat, 2008

How to cite data from ETD in your scientific paper

All data available at this site were obtained from published literature or from open on-line sources (TRESCA, AXA) and can be used freely for scientific purposes.

If you find Exoplanet Transit Database useful for your work, please type the REFERENCE as follows:

Poddany S., Brat L., Pejcha O., New Astronomy 15 (2010), pp. 297-301,
Exoplanet Transit Database. Reduction and processing of the photometric data of exoplanet transits (arXiv:0909.2548v1)

While using data from Exoplanet Transit Database in your publication, please type the REFERENCE as follows:
- If transit observation was captured from published literature / paper, you can find reference in column "Author & REFERENCE", so the source paper should be cited in common way.
- If transit observation was published in some on-line source (AXA, TRESCA), ask observers for a permission and other useful comments about the data. We can supply you with e-mail contact to observer if necessary.
