Based on the derivatives calculated here, JaP made a response matrix. Using response matrix, he developed a set of revised optics settings for the 3-140 beamline:

corrections:
25% of correction - Run 9655,
50% of correction - Run 9656,
100% of correction - Run 9657.

I also try only Q789 correction:
25% correction 9658.
