Hi,
1) sureduce assumes that the offset is in meters and the reduction
velocity in km/s. (or anything else with a ratio of 1000). Are the
offsets in meters ? The geometry of this collection looks very strange
(>100 km offset), with a recording of only 8s.
2) How can your data exhibit varying offsets with constant source and
receiver locations ?
Check the geometry of your traces and try again.

Hello greetings! I am a beginner. I have a big su file
with huge shot points, but I want to see a particular shot point in reduced velocity mode.
I made a single file for those particular shot by using key=fldr. Now this file should
have total 636 traces. I wrote a command suwind < indut su file key=tracl max=636
.......
However, in image I got values from2.84*10^5 to 2.85*10^5. Even when I want to see the
image in reduced velocity mode, I need to set rv= >1000 whereas it should be rv=1 to
2. It seems like there are something wrong with units in the headers. Would anyone please
help me with how can I fix these??? I am a new user; I will appreciate your help and time.
Here I attached the header info. Thanks
FYI
636 traces:
tracl 1 636 (1-636)
tracr 284929 285564 (284929-285564)
fldr 2245
tracf 1 636 (1-636)
cdp 2245
offset 112464 120401 (112464-120401)
sx 376962
sy 5176643
gx 376962
gy 5176643
ns 2001
dt 4000
