.. currentmodule:: eqcorrscan.core.lag_calc
.. automodule:: eqcorrscan.core.lag_calc

Functions for generating pick-corrections from cross-correlations with a
template.  Originally this was designed for events detected by matched-filtering,
however you can use any well correlated events.  Based on the method of
`Shelly and Hardebeck (2010)`_.
