The survey design of the profile used in this reflection experiment. Shot points and receiver settings are displayed. The solid bars at the bottom of the figure indicate the parts of the profile used in analyses for the deep and the shallow sections. The data processed for the shallow section are taken mainly from a part where both the vibration points and the receivers are deployed at 25-m intervals.
