2. VH
E(v´) VL
Effects of shifting VH and VL relative to E(v´) (for constant W, a and g (g = 0)) on IR
is explored below:

3. Up shift of VH,
Modified NEW model Vs
OLD Model:

4. Up shift of H, Modified NEW model Vs OLD Model:
W=152,gamma=0, alfa = 0.88
+ shift of VH:
cH2/cL2 IR
Modified NEW
J´+1
OLD

5. Up shift of H, Modified NEW model Vs OLD Model:
W=152,gamma=0, alfa = 0.88
+ shift of VH:
100
cH2/cL2 IR
Modified NEW
J´+1
OLD

6. Up shift of H, Modified NEW model Vs OLD Model:
W=152,gamma=0, alfa = 0.88
+ shift of VH:
250
cH2/cL2 IR
Modified NEW
J´+1
OLD

7. Up shift of H, Modified NEW model Vs OLD Model:
W=152,gamma=0, alfa = 0.88
+ shift of VH:
cH2/cL2 IR

8. Up shift of VL,
Modified NEW model Vs
OLD Model:

9. Up shift of L, Modified NEW model Vs OLD Model: Modified NEW OLD
cH2/cL2 IR
Modified NEW

OLD

10. Up shift of L, Modified NEW model Vs OLD Model: Modified NEW OLD
cH2/cL2 IR
Modified NEW
J´+1
OLD

11. Up shift of L, Modified NEW model Vs OLD Model: Modified NEW OLD
cH2/cL2 IR
Modified NEW
J´+1

12. Shape of IR vs J´ almost same for “Modified NEW model” and “OLD model”.
cL2 an cH2 are the same (by definition) in both models.
c12 differs in the models.
Absolute IR-values differ => a values will differ (these are power dependent anyway)
=> g and W which are “shape dependent parameters” should be almost the same for same
“IR vs J´shapes”.
ERGO: OLD model is more favourable.
It has the advantage to give H and L contributions to the IR
