Hypoellipse setup

The Hypoellipse earthquake location program was used making the following changes in the test:

TEST
MEANING
DEFAULT SELECTED VALUE
2 elevation correction (< 0 no elev cor; = 0 use 1st vel; > 0 use this). 5 0
10 apply distance weighting on this iteration. 50 1
11 xnear = greatest distance with weight of 1.0. 50 50
12 xfar = least distnace with weight of 0.0. 100 150
14 weight out large residuals on this iteration. 50 5
15 give zero weight to residuals > this. 10 3
18 begin jeffreys weighting on this iteration. 50 3
19 use jeffreys weighting only if rms > this. 0,05 0,2
21 maximum number of iterations. 9 30
31 duration magnitude c1, constant. - 1,15 -1,8
32 duration magnitude c2, *log((f - p)*fmgc). 2,0 2,41
