data presented for a ^ 6.0 were computed by the National Bureau of Standards, 4 the 

 remaining data were computed by Houghton and Chalker and constitute a revision of an 

 earlier work by Stratton and Houghton. 6 



Houghton and Chalker have fitted a smoothed curve of the type suggested by Van de 

 Hulst 6 to the computed points and then extended it somewhat. This curve is given below.
