Definition K_eta #71

Open Jannekedelaat opened 5 years ago

Jannekedelaat commented 5 years ago

Hi,

I was looking into the methodology of MC_Kernel, and comparing that to the equations given in Fichtner 2011. What I noticed is that kernel K_eta is slightly different defined in MC_Kernel than in Fichtner 2011: MCKernel: 2*\rho ( v{ph}^2 - v_{sh}^2 ) Kc Fichtner: \rho ( v{ph}^2 - 2*v_{sh}^2 ) K_c Is this a bug or is there a reason this kernel is differently defined?

Cheers,

Janneke

My feeling is that the definition of K_eta you have supplied above from Fichtner is its general definition. K_eta as coded is the definition of K_eta for an isotropic reference medium.
