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
