Documentation
Stretch of the time axis.

 
Synopsis
        sfstretch < in.rsf > out.rsf datum=dat.rsf inv=n dens=1 verb=y v0= half=y CDPtype= delay= tdelay= hdelay= scale= nout=dens*n1 extend=4 mute=0 maxstr=0 rule=

 
Parameters
       
 
int CDPtype=

 
file datum=
auxiliary input file name
 
float delay=
time delay for rule=lmo
 
int dens=1
axis stretching factor
 
int extend=4
trace extension
 
bool half=y [y/n]
if y, the second axis is half-offset instead of full offset
 
float hdelay=
offset delay for rule=rad
 
bool inv=n [y/n]
if y, do inverse stretching
 
float maxstr=0
maximum stretch
 
int mute=0
tapering size
 
int nout=dens*n1
output axis length (if inv=n)
 
string rule=
Stretch rule:
n - constant-velocity normal moveout (nmostretch), default
l - linear moveout (lmostretch)
L - logarithmic stretch (logstretch)
2 - t^2 stretch (t2stretch)
c - t^2 chebyshev stretch (t2chebstretch)
r - radial moveout (radstretch)
d - datuming (datstretch)
s - s*t scaling stretch (scalestretch)

 
float scale=
scaling factor for rule=scale
 
float tdelay=
time delay for rule=rad
 
float v0=
moveout velocity
 
bool verb=y [y/n]
verbosity flag
