refined kappa Her scan

Took several more cuts at the frames of double star κ Herculis in the BinStar software. Was increasingly choosy about the data I allowed.

Got the separation down to 28.78 with a position angle of 12.07 using 210 data points. But that's over 1 arc-second off. Just under 1 degree for the PA.

I think this is pretty well the best I can do...
