B-G multi: Backus-Gilbert multi-parameter

B-G multi is a multi-parameter version of the classical Backus-Gilbert method, which is concerned with inferences of one physical parameter class only. The method rests on the solution of a joint optimisation problem that tries to maximise deltaness for the parameter of interest, while minimising trade-offs with all remaining parameters. We tested and developed the method using surface wave dispersion data collected by Distributed Acoustic Sensing on the Northeast Greenland Ice Stream.
