Interpolation in Pub.229

[pabrides]

I used sun 1 and moon 3 this time and came within 2 nm of the true position.  Here is the plot - I can add the reduction figures upon request.  ...  As you can see I improved the scale to make the reduction more accurate.  This was a sneaky little problem, but Im glad I took the time to work it out.  I learned a valuable lesson... dont take anything for granted when doing a reduction... double check everything.
