Details

18 guns each source array

Near Channel Number for each streamer is 468, 936, 1404, 1872

Record Length for Sequence 1 (AXIS1) is 8 seconds. The rest of the lines were recorded for 10 seconds. Cable Depth is 7.5m for Sequence 1, 2, 3, 4 (AXIS1, AXIS2, AXIS3, AXIS2R1), 15m for Sequence 5 (Transit1). Cable Depth was 10m for the rest of the lines

Source to Near Channel Distance is given as an approximation, use P1/P2 files for greater accuracy.
