Selects which rows in the hypocenter determination to keep during non-linear itaerations based on robust rsidual elimination.

1 | ```
Rowz2Keep(Ldat, EQ, G1, RESMAX)
``` |

`Ldat` |
List of station arrivals |

`EQ` |
Earthquake location |

`G1` |
derivative and travel time estimates |

`RESMAX` |
2-vector for P and S-wave residual maxima |

This is a utility used internally.

Residuals greater than the respective maxima provided are eliminated in the svd inversion. If fewer than 4 remain, the smallest 4 rows are returned.
