[ncl-talk] ContourPlotDraw: ARSCAM/ARPRAM - ALGORITHM FAILURE

[Wei Huang]

Dave,

If we edit file:  arpram.f, and
Change line:
              IF (.NOT.(KF1.NE.0)) GO TO 10224
to
              IF (KF1.NE.0) GO TO 10224
NCL can run through, but the image generated has some noise.

This is not a fix, but kind of a point where the problem is come from.

Thanks for looking into this.

Wei Huang
