is always positive. Although table 6 is computed for the epoch, 
January 1, 1900, it is applicable without material error for any series 
of observations. 
311. The values of u of L, and u of M,, may be obtained from table 
13 for any date between 1900 and 2000, inclusive, using the value of N 
for interpolation. If the series falls beyond the limits of this table, 
the following formulas may be used: 
u of L,=2&—2v—R (par. 129) (446) 
u of M,y=é—v+ Q (par. 123) (447) 
The values of & and vy may be taken from form 244, the values of R 
and Q from tables 8 and 10, respectively, using the arguments J and 
P for the middle of the series.
