How to find the resolution points for turbine check in CAESAR II based on NEMA SM23?

[Mehr_1139]

In order to have an equipment check for turbines, CAESAR II requires us to enter DX, DY & DZ (distances between turbine nozzles and the resolution point). Regarding how we can find the location of the resolution point, NEMA SM23 doesn’t provide any helpful guideline. Finally, in a booklet, I found an example in this regard. This example only has a figure with no extra explanation! I enclose this figure to my post, please have a look at it and let me know if you get how it calculated the resolution point.
Any guidance of finding the resolution point is highly appreciated.

P.S.: In the figure enclosed, the shaft is in the X direction, if we assume it's exactly in the middle of Inlet and outlet nozzles, so the Z coordination of the resolution point is 250 (which is in compatible with the figure). what it's in ambiguity is the Y coordination which I have no clue for.

Have you gone through the NEMA SM23 sections of the Caesar II user guide and applications guide?
