 WAVE LENGTHS OF FRAUNHOFER LINES 



For convenience of reference the values of the wave lengths corresponding to the Fraun- 

 hofer lines usually designated by the letters in the column headed "index letters," are here 

 tabulated separately. The values are in International Angstrom units. The table is for the 

 most part taken from St. John's revision of Rowland's table of standard wave lengths (1928). 



The solar intensities of the lines of the 4th column are: G, 6, 3; g, 20; h, 40; H, 700; 

 K, 1000; L, 25; M, 4; N, 30; O, 15; P, 3; Q- 7; R, 3. 5; S, 3, 4. 6; s, 20; T, 3.
