Dear Sirs,
I have a seismic data sampled at micro-seconds.
I load 3 files with :
segyread tape=mySegy.sgy > mySegy.su
Then I used:
surange < mySegy.su
As you can see in the attached log files, the one called box31.log contains
"strange" d1 and f1 values.
Please could you help me to understand why d1 and f1 are so big ?
The only one significant difference is that an01 and an31 are sampled at 33
micro-seconds while box31 is at 124 micro-seconds.
Thanks
Giulia

Hello,
Thank you so much for your consideration. I attached the screenshot what I got adding key1=sy. I also attached the range of my original file where sy is missing. I don’t have access to my computer right now, so I just attached the screenshot from my phone, I apologize for that.
Thanks. I am looking forward to hearing from you.
Sincerely,
Elora

Hi Elora - It might help us to see the output of surange. David

Hello Everyone,
Greetings. I have a su file where sy header is missing. How can I set a correcect sy values? I went through sushw and suchw and saw some basic information. I tried Key1=sy, key2=sx and key3=gx but noticed that I got gy values but gx and gy are same which is not supposed to be. I do not know the first value of gy. I request you to help me to set gy values.
Thank you.
Sincerely,
Elora

Elora,
I am rather amazed about your question. The sushw program is very versatile in generating traceheaders for complicated geometry as well as using values from a textfile for traceheaders. If you have the values for sy in a simple textfile in one column, try a2b < your_text_file n1=1 > binary_file, followed by sushw < your_su_file infile=binary_file key=sx > your_amended_su_file.
Check results by applying sugethw < your_amended_su_file key=sx,sy,gx,gy output=geom > resulting_header_file.txt. That shoud result in a four-column text file
Good luck
