I checked PR3 TFs for the final health check (fig1-33).
Since current IM V2 input value (5500 cnts) is slightly lower than the other vertical OSEMs (6500), IM V2 gain is slightly lower tha before (about 2dB).
Also, GAS resonances are slightly shifted maybe due to the thermal drift of GAS position but they seem also acceptable.
Other than the above, TFs are well matched with the reference.
