This is the data release for the PSP rotor suction-side transition data. 
The correct reference is:
Gardner, A.D., Weiss, A., Heineck, J.T., Overmeyer, A.D., Spooner, H.R., Jain, R.K., Wolf, C.C., Raffel, M. "Boundary layer transition measured by DIT on the PSP rotor in forward flight", submitted to Journal of the American Helicopter Society 2020 (Please update when citing)

The data is point 142 and was taken on 19.04.2018 as part of the NASA-DLR cooperation on measurement techniques.
Data was provided to the DLR by Austin Overmeyer.
Additional data from JT Heineck and Hannah Spooner.
Markus Raffel from DLR was present at the experiments.
Data reference point identification and overlap was done by Armin Weiss
Additional data analysis, boundary layer transition position extraction and DIT analysis was performed by Tony Gardner.
Note that this data includes transition on blades 2 and 3, swapping between the blades halfway through the experiment
Note that the blade hinge point is +0.5 inch compared to some earlier experiments (r=67 inch)
Note that for x/c, the origin of the x position, and the chord length c is the same for all cuts, so that it builds a rectilinear coordinate system. On the blade tip This means that the leading edge is then at x/c~0.5, which is a bit contraintuitive, but helps with the plotting.
This data is from Rohit Jain who computed the case using RCAS:
