325. The x’s of K, and S, are to be corrected by the accelerations as 
indicated before entering in column (4), and in computing item (14) 
for the diurnal constituents and (21) for the semidiurnal constituents 
the corrected x’s are to be used. If the two angles in item (14) for 
the diurnal constituents, or in items (20) or (21) for the semidiurnal 
constituents, differ by more than 180°, the smaller angle should be 
increased by 360° before taking the difference, which may be either 
positive or negative. In computing column (8) it will be noted that 
the corrected log R’s of K, and S, are to be used in inferring other 
constituents depending upon them. 
326. Form 245, Elimination of component effects (fig. 19).—This 
form is based upon formulas (389) and (390). One side of the form 
is designed for the elimination of the effects of the diurnal constitu- 
ents upon each other and the other side for use with the semidiurnal 
constituents, the two sides being similar except for the listing of the

If the series is less than 355 days, omit 2SM._ For all short series, the values in columns (4) 8 -2726 
and (8) will be computed in accordance with the Equivalents and Factors in columns (3) and (7), 
respectively; but if the series is 192 days or more in le! , the x of K, for column (4) and the +7.8461 
log. R of K, for column (8) may be taken directly from Form 194; and if the series is 365 days or S 
more in length, the « and log. R of all the components for which analysis has been made may +0 -09 
be taken directly from the eame form. When a value is thus taken directly from the analyais, 7 -9404 
the corresponding equivalent in column (3) and factors in column (7) should be crossed ont. 
The tabular values for (14) to (18) may be obtained from Tables 23 to 26 in Special Publi-
