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 _______________________________________________ Seisunix mailing list --seisunix@mailman.seismic-unix.org To unsubscribe send an email toseisunix-leave@mailman.seismic-unix.org
