#71 closed defect (fixed)

problem with AS 2008 when rupWidth=0

Reported by: Kevin Milner Owned by: Peter Powers

AS 2008 gives NaN's when rupWidth=0 due to this code. How should it be modified to fix this?

When rupWidth=0, then rXtest=0, and T2 becomes NaN because of a div by zero.

in getMean from trunk/src/org/opensha/sha/imr/attenRelImpl/

//T2 (Eq. 9) - rewritten 2009-01-29 to be consistent with ES paper
double rXtest = rupWidth*Math.cos(Math.toRadians(dip));
if (rX>rXtest || dip==90.0) {	// if site is beyond the surface projection
	T2 = 1.0;
} else {
	T2 = 0.5 + rX / (2.0*rXtest);
