Fig. 9.30 Spline-curves for
positions of RASC distance
values in three sections
obtained by means of
indirect method. (a) Morgan
Creek section. Curve of
Fig. 9.29 was combined
with curve for positions
of event levels according to
method of Fig. 9.25 . Second
(cf. Fig. 9.25b ) and third
(cf. Fig. 9.25e ) smoothing
factors were set equal to
0.02 and 0.2, respectively.
Final standard deviation
of deviations from curve
is SD
