barycorr.py

Python routines that query Jason Eastman's web applets for barycentric velocity and time correction ( barycorr.pro, utc2bjd.pro and bjd2utc.pro)

When using one of the services provided through this module, please cite the corresponding paper:

The Python interface is written by René Tronsgaard (Aarhus University) and may be used, modified or redistributed without restrictions.
