Looking at the example script https://wiki.reallusion.com/IC_Python_API:RLPy_RIHandDevice I am looking for an explanation of the t_pose_data and frame_data

1) What is the format of the frame_data?
frame_data = [-0.05, 106.89, -3.65, -6.91, 173.25, -1.78, -11.44, -1.88, -0.06, -6.14, 12.7, -9.17]   what do the coordinates mean?   xyz of bone? max min values?

2) What is the format of the t_pose_data?

Thanks
