Fit between modelled and picked traveltimes after 20 WET iterations : 

RMS error : 1.57 millisecs.
Normalized RMS error : 1.68 percent (RMS error, divided by average pick time of all traces modelled)

Relative misfit function : 2.48 millisecs. (Gerard T. Schuster 1993 p. 1315; squared error summed over all traces modelled,  divided by the modelled trace count)
Maximum absolute error : 7.97 millisecs., for trace 005-030 (Shot#-Trace#) in database D:\ray32\SAGEEP11\SEIS32

# of traces modelled : 10100

Increase the WET iteration count for improved output. See

Also edit velocity smoothing : test changing 'Smooth nth iteration' to 5 or 10 from default 1 for less smoothing.

Use overlapping receiver spreads with profile-internal far-offset shots for deeper and more reliable imaging. See
