VELCONV - VELocity CONVersion

velconv <infile >outfile intype= outtype= [optional parameters]

Required Parameters:
intype= input data type (see valid types below)
outtype= output data type (see valid types below)

Valid types for input and output data are:
vintt interval velocity as a function of time
vrmst RMS velocity as a function of time
vintz velocity as a function of depth
zt depth as a function of time
tz time as a function of depth

Optional Parameters:
nt=all number of time samples
dt=1.0 time sampling interval
ft=0.0 first time
nz=all number of depth samples
dz=1.0 depth sampling interval
fz=0.0 first depth
nx=all number of traces

Example: "intype=vintz outtype=vrmst" converts an interval velocity
function of depth to an RMS velocity function of time.

Notes: nt, dt, and ft are used only for input and output functions
of time; you need specify these only for vintt, vrmst, orzt.
Likewise, nz, dz, and fz are used only for input and output
functions of depth.
