Please excuse me if this is a very dumb question, but... where is the program?

This will actually show up as a formatted table if you use a fixed-width font and an external editor. It will not work with hpmuseum's message editor and "visual formatting", especially not with a mixture of tabs and spaces.

Code:

Angle (deg)     Rectangular     Trapezoidal     Circular (center)     Circular radius
  0 (tongue)    R=0.1750        R=0.1750        a=0.1750             r=0.0000
 90             R=0.3167        R=0.2230        a=0.1924             r=0.0174
180             R=0.8965        R=0.2555        a=0.2000             r=0.0250
270                             R=0.2843        a=0.2060             r=0.0310
360 (throat)                    R=0.3115        a=0.2111             r=0.0361

I hope this is what you wanted to show, but I'm not sure since there are some characters that cannot be displayed.
