STANDARD SOLAR WAVE LENGTHS. INTERNATIONAL ANGSTROMS 



Adopted at the Leyden Meeting of the International Astronomical Union. 

 See Trans. Int. Astron. Union. 3, 93, 1929. 



The solar wave lengths in the Rowland Revision by St. John (and others) are based upon 

 the former arc standards and require the folllwing corrections to reduce them to the scale 

 of the following adopted lines: 



X 3592 to X 5625 A.

In the following table the + sign following the designation of an element indicates the state 

 of ionization; an indication like Fe — , solar line too strong to be due to iron alone; Fe, Co, 

 coincidences of like order; Fe Co, coincidence closer for preceding element; Fe Co, Fe line 

 to the red, Co, to the violet; an italicized element indicates predominence of that element.
