Dear Scott,
	Thanks for finding that error in the interpolation
routines. Please kill line 70 in "getmodel.f" and replace it
with these two lines:

      if ( ja.eq.5 .and. jz.lt.6) ja=6
      if ( ja.lt.6 .and. jz.eq.5) jz=6

and recompile and that should fix it. It wasn't picking quite
the right grid corners around that nasty missing block in age-Z
space.

Yours,
Guy

All my best, hope the thesis is coming well!
