Model Parameters
...
Model Parameters:
- M = { VO , ED , yyW , xW , xG , yW , xJ , JW0 } – totally7 constants , kro(s), krw(s) } – totally 8 constants and two arrays
Restrictions:
- all constants are positive
- 0 < kro(s) < 1, 0 < krw(s) < 1
Model fitting

Source data corrections:
...
P = Pi + ( yW ‧ Bw ‧ ΣQW↓ + Bo ‧ ΣQO↑ + xW ‧ Bw ‧ ΣQW↑ + xG ‧ Bg ‧ ΣQG↑ )‧ Pi ‧ xP /VO
d = DFO = ΣQs = soi + (sor - swi) ‧ ED ‧ ΣQO↑ / VO
JO = kro(ds) ‧ xJ
JW = JW0 + krw(ds) ‧ xJ
JG = Rs ‧ JO
kro(d), krw(d) are set by tables or RPM Corey @model.
