 This will use the data already on disk and recalculate the correlation using a different clock offset. Once you have the good clock offsets, its is worth adding them to your "config" file. This will use the data already on disk and recalculate the correlation using a different clock offset.

 If you get impatient due to a slow download, you can "recorr" before the data has arrived.
