psmeca color spilling over + modifying text string
I am trying to plot a moment tensor with the compression quadrant colored black. However, the color spills over the focal sphere. Note that my moment tensor has a large isotropic component, but this is intentional. I am using Version 5.4.2 (r18461) and here's my code. How do I fix this? Also, how do you change the text string attributes (position/size/font). There are no notes on this in the manual. Thank you!

Apparently the large isotropic moment is a problem. The original developers of psmeca are not very involved anymore but wrote:
Here is the snippet from utilmeca.c f = - v / v[d]; iso = vi / v[d]; jp_flag = 0; djp = -1; mjp = -1; /* Cliff Frohlich, Seismological Research letters, * Vol 7, Number 1, January-February, 1996 * Unless the isotropic parameter lies in the range * between -1 and 1 - f there will be no nodes whatsoever */ Frolich, C.

I attach the paper and perhaps you may have suggestions?
