WARNING: the ASTEP Lightcurve Database Service is under development.

Please report any problem or send comments to .

Summary — this page is the entry point to the ASTEP Lightcurve Database Service. The service allows users to search for lightcurves in the ASTEP database. Note that only ASTEP 400 telescope data from 2010 until 2012 is currently available.

Description —  A-STEP is a 40 cm photometric telescope installed at Concordia station on the Antarctic plateau (Dome C). It has been operated 4 years between 2010 and 2013. Informations on A-STEP can be found here.

ASTEP has a field of 1° x 1° on the sky, imaged on a 4096x4096 pixels detector. More than 50 fields were observed during the first three years of operation for periods of two weeks up to two months. Among them, 25 were observed for a research of extra-solar planet transit. 43 planet candidates were identified. The candidate list is accessible here.

You may also read the description of all fields in the database.

Quick Tutorial — For all users. Follow this link for help about the use of the service. You can also use directly the shortcuts below.

Advanced Help — For autorized users only. Here, you will find useful information on how to manipulate, deploy and update the database.
