DR. VV. M. HICKS: A CRITICAL STUDY OF SPECTRAL SEKIKS 



TAIU,K 1 1 . (continued). 



Since the publication of [I.] RANDAU.* has measured P(l) with considerable accuracy. This, with 

 P(2, 3), gives PI(OO) = 31401-78, and RANDAI.I.'S v;ilue for PI(!) gives VP(1) - 19673-12. BKVAN'S 

 observations show PI() about 2 larger. Probably, however, this value for VP(1) is close to the true 

 value for D( <x ), and the calculations are based on D( oo ) 19673-00. 



For D, (3) LKHHANN gives denominators 548 larger for DM and 548 less for D !2 . If we allow S. twice 

 the weight of L. the value of O - C would come out about zero. 



Cu. 

 A = 7311. &= 146-22. 



D(oo) = 31515-48 found from K.R.'s value for D(2, 3, 4). 



A = 27791. 



S = 421-07. 



t Calculated from D* - v. 



D( oo ) found from first three by formula = 30644-66, modified to 30644-76. 

 The limit uncertain, see special discussion (p. 403). 



The observation errors after the first are so large that the satellite differences might be also 238,, or 

 larger, us in Cu.
