            Check the ts_mtm2_matlab_tools for the configuration tool provided by Harris.

            For the hardpoint correction between the surrogate the mirror, I think the main difference is the stiff matrices:

            1. Mirror: https://github.com/lsst-ts/ts_mtm2_matlab_tools/blob/develop/ReferenceFiles/StiffnessMatrix_M2.mat

            2. Surrogate: https://github.com/lsst-ts/ts_mtm2_matlab_tools/blob/develop/ReferenceFiles/StiffnessMatrix_Surrogate.mat

            I think we could do the run-time calculation of different hard points based on the following calculation:
            https://github.com/lsst-ts/ts_mtm2_matlab_tools/blob/develop/Utilities/CalcHPFCInfMat.m

            As the expectation, some parameter files are duplicated:

            For the LUT files, most of them between the mirror and surrogate are the same:

            The only difference is the F_F.csv. Based on the Harris EUI user manual, this is: "Force Look Up Table for Factory Force Offset".

            For the surrogate, all the elements in F_F.csv are 0.

            Check: 03_M2_correctability_analysis.pdf.
