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
Dear all,
I have performed a time resample of some 500ns sampled 3D seismic data to
1ms intervals using the suresamp command as shown below, but was unable to
transcribe the 189-192 bytes of the Inline and the 192-196 bytes of the
crossline numbers.
segyread tape=Source3D.sgy|suresamp rf=0.5|segyhdrs|segywrite
tape=Output3D_1ms.sgy
I solved this problem by using the ASCII input/output function for trace
header on SeiSee, a free Windows software, to write out the header
information of the original file and then write it into the header of the
output file.
Is there a way to transcribe inline and crossline numbers using the SU
function?

Hello, I am a beginner. I need to apply sureduce command to a particular shot which is in su file format. I tried with different rv values but could not see any differences in the image. I checked with the headers of that file and found I have ns and dt headers but not offset. Can anyone please help me how can I add offset header to my su file? And please let me know if there are any other things to fix to get result. Thanks
Hi SU users
The SU list manager is broken. At least no new subscription is possible.
The las one is dated 09/23. Sticking to mailman2 inhibits the upgrade of
the whole hosting system (yunohost.org).
I plan to upgrade to mailman3 soon, keeping as much information as
possible from the present mail server.
Don't worry if you receive automatic or test messages in the next hours
or days.
D.
BTW: I don't know if this message will be transmitted :-)
