, fgy = 1-388, that is, £f= 1-397, Ag v =— 0-6 per cent. 
aU Xgx = 1 '647, that is, ff = 1-657, Ag x = - o-6 per cent. 
The calculated positions of the components are 
± (01302) (0-3905) (0-6508) 0-7460 i-oo6 1-276 1-527 1-787 2-047. 
A = 3839-777. The Zeeman pattern of this line is Type 6 inverted. 
The measurements were 
± 1-337 (1-987). 
There being only one ^-component it follows that i x = i v = I and 
kx-ky = 1-987 
kx + ky = 1 ’337» 
therefore 
rg x = 3-324, that is, V = 3-333, Ag x =- 0-3 per cent. 
=— 0-650, that is, — f ==— 0-667, Ag u =— 2-8 per cent. 
These rational numbers give the following positions of the components 
± 1-333 (2-000). 
The large deviation in the case of g y can be explained by the poor 
accuracy ‘of measurement with only four components altogether. 
A =3841-081. Completely resolved. The components had the 
positions 
±(0-2794) 0-4831 (0-8316) 1-037 1-592 2-146, 
and this conforms to Type 4 with i x = 2 and i v = 3. Consequently 
we have 
*gx ~ kv — 0 -83 1 6 
k* - ky = - 0-4831, 
and 
Ig y = I-3I5, that is = I-3H, Agy = + °'°7 per cent. 
{g x = 1-869, that is ff = 1-867, Ag x — + O-l per cent. 
These values give 
±(0-2762) 0-4857 (0-8286) 1-038 1-590 2-143. 
A = 3843-985. Completely resolved. The components had the 
positions 
±0-076 (1-135) 2-199. 
This conforms to Type 4 with i x = 1 and i y = 2, and we have 
kx~ kv= 1*135 
kx+ky = 2-199,
