I have a script I am using for Zero Offset VSP processing. First of all, my first three traces looked cut so I rejected them. After getting rejected file, I filtered out the downgoing wavefield by sudipfilt. Then, I picked arrivals on the zero amplitude line corresponding to picking amplitudes. Then, I converted those arrival times (seconds) to milliseconds and saving them in a txt.file. After that, txt file is converted from ascii to binary format. Finally, I am adding those time values to the traces by sustatic command.

At this point, however, when I try to plot the flattened upgoings, the script plots just a so narrow part as follows:

Can you help me with this issue? I tried to change a lot of things but I could not get whole flattened upgoings. 

 If you would like to check my script, I added here.
