SYNOPSIS
SEISMIC UNIX NOTES SUZTOT - resample from depth to time
suztot <stdin >stdout [optional parms]
Optional Parameters:
nt=1+(nz-1)*2.0*dz/(vmax*dt) number of time samples in output
dt=2*dz/vmin time sampling interval (defaults avoids aliasing)
ft=2*fz/v(fz) first time sample
z=0.0,... depths corresponding to interval velocities in v
v=1500.0,... interval velocities corresponding to depths in v
vfile= binary (non-ascii) file containing velocities v(z)
verbose=0 >0 to print depth sampling information
Notes:
Default value of nt set to avoid aliasing
The z and v arrays specify an interval velocity function of depth.
Note that z and v are given as arrays of floats separated by commas,
for example:
z=0.0,100,200,... v=1500.0,1720.0,1833.5,... with the number of z values
equaling the number of v values. The velocities are linearly interpolated
to produce a piecewise linear v(z) profile. This fact must be taken into
account when attempting to use this program as the inverse of suttoz.
Linear interpolation and constant extrapolation is used to determine
interval velocities at times not specified. Values specified in z
must increase monotonically.
Alternatively, interval velocities may be stored in a binary file
containing one velocity for every time sample. If vfile is specified,
then the z and v arrays are ignored.
see the selfdoc of suttoz for time to depth conversion
