Processing flow for 8 magnetometers towed together

Hi,

We are acquiring magnetometer data from 8 x G882 magnetometers, towed from 2 x EIVA Katria scan fishes, 4 magnetometers in each EIVA Katria scan fish.

The data logging is in Qinsy which is producing 2 files per line, one for each Katria.

The logged files has the final position, altitude, depth, signal and the total field for each of the magnetometers.

The objective of the survey is UXO detection.

Please suggest an ideal processing work flow for this project.

Thanks
