bright_lights¶
Code to determine the brightness function of seismic data according to a three-dimensional travel-time grid. This travel-time grid can be generated using the grid2time function of the NonLinLoc package by Anthony Lomax which can be found here: NonLinLoc. NonLinLoc is not distributed within this package but it is a very useful stand-alone library for seismic event location.
This code is based on the method of Frank & Shapiro 2014.

Private Functions¶
Note that these functions are not designed for public use and may change at any point.
_rms |
Calculate RMS of array. |
_rm_similarlags |
Remove nodes that have a very similar network moveout to another node. |
