given an earthquake hypocenter and a list of station information, retrieve the station residuals.

1 |

`XY` |
matrix of station location and arrival times. |

`vel` |
list, RSEIS velocity model |

`h1` |
hypocenter location, c(x,y,z,t) |

`PLOT` |
logical, TRUE=plot the residuals |

The XY mtrix is in cartesian coordinates, i.e. it has been projected into units of km. Only 1D velocity models are used at this time. Only residuals of P and S wave arrivals are estimated.

vector, right hand side of the least squares problem.
