Kepler K2 Light Curves reduced by the HAT team

This page lists all base light curve data for the Kepler K2 mission derived by our team using tools developed for the HATNet and HATSouth exoplanet surveys. As light curves for each K2 campaign field are reduced, we'll make them available for direct download here. If you use these data, please cite the papers listed in the table below for each data release.

How do I enter coordinates?

Use J2000 coordinates in either decimal or sexagesimal formats and an optional search radius in decimal arcminutes. The maximum search radius is 300 arcminutes = 5 degrees. The default search radius is 5 arcminutes if one is not specified.

Decimal coordinates
[DD]D.ddd... +/-[D]D.ddd... DD.dd...
example: 172.0 +0.55 5.0
Sexagesimal coordinates
HH:MM:SS.sss... +/-DD:MM:SS.sss... DD.dd...
HH MM SS.sss... +/-DD MM SS.sss... DD.dd...
HH:MM:SS +/-DD:MM:SS DD.dd...
HH MM SS +/-DD MM SS DD.dd...
example: 11:45:00 +00:30:00 15.0
Which object identifiers can I use?

You can use 2MASS, UCAC4, and Kepler EPIC identifiers.

2MASS object ID
JXXXXXXXX[+-]YYYYYYY
example: J06055652+2420201
UCAC4 object ID
UCAC4-XXX-YYYYYY
example: UCAC4-454-050262
Kepler EPIC object ID
EPICXXXXYYYYY
example: EPIC201494016
