This is a preliminary release of the regressionRelLoc code on https://github.com/stevenjgibbons/regressionRelLoc It is a collection of FORTRAN77 programs to solve for the relative locations of seismic events and the corresponding best-fitting slowness vectors. The main program for iterative solution of both locations and slowness vectors, from an initial specification of slowness vectors, is called regressionRelLoc. The program fixedSlovecsEventSolve solves for a set of events for a given set of fixed slowness vectors. The program fixedEventsSlovecsSolve solves for the optimal slowness vectors for a given set of event locations. (regressionRelLoc basically iterates between the operations performed in fixedSlovecsEventSolve and the operations performed in fixedEventsSlovecsSolve.) There are two additional programs, oneEventPairVectorSolve and oneSlovecPairVectorSolve, which were basically written for unit testing of the operations in regressionRelLoc. Before we call the codes, we need to define a set of slowness vectors. The program statphase2slowvec (https://github.com/stevenjgibbons/statphase2slowvec) will calculate the slowness vectors for a set of stations and phases using the ak135 model. The Cartesian output can be transformed back to geographical space using the xy2latlon.py program in this repository.

Two test cases are provided: a set of surface explosions in northern Finland and the DPRK nuclear tests.
