Hello, SAC users. I could use some advice about how to line up a group of
traces while assigning picks. I've got 10 similar traces and I want to line
them up on prelimary P picks so I can correct the bad ones, but "ppk rel p 10"
lines traces up on "o". I can't find a way to change this or rewindow the data
without destroying the files' "o" times. Does anyone know of a workaround?
