CVM-S4.26 Proposed Final Model

Description

The CVM-S4.26 proposed final model was first described by Tom Jordan as an effort to integrate Po's perturbations while still honoring the CVM-S4 GTL.

Algorithm

The proposed final model incorporates Po's 26th iteration in the following manner:

BASE Vp, Vs, Rho = CVM-S4 material properties
STARTING Vp, Vs, Rho = Po and En-Jui's starting model from which all the iterations were derived
FINAL Vp, Vs, Rho = Returned material properties
PERTURBATION Vp, Vs, Rho = Po and En-Jui's 26th iteration of perturbations

IF BASE Vs < 1000m/s THEN
    IF BASE Vs + PERTURBATION Vs < BASE Vs THEN
        FINAL Vp = BASE Vp
        FINAL Vs = BASE Vs
        FINAL Rho = BASE Rho
    ELSE
        FINAL Vp = BASE Vp + PERTURBATION Vp
        FINAL Vs = BASE Vs + PERTURBATION Vs
        FINAL Rho = BASE Rho + PERTURBATION Rho
    END IF
ELSE
    FINAL Vp = STARTING Vp + PERTURBATION Vp
    FINAL Vs = STARTING Vs + PERTURBATION Vs
    FINAL Rho = STARTING Rho + PERTURBATION Rho
END IF
