FWI with density and/or Q-factor

[kerim371]

Hi,

I'm wondering is it possible to run FWI with density (and possibly Q-factor) so that after each iteration both slowness and density is updated?
I can see there is an fwi_example_constraints.jl - is this what I'm looking for?

You can currently propagate with density and Q but only the sensitivity w.r.t velocity are implemented. For density you can usually get away with Gardner relationship
