radar_use_dims = [0, 1, 2, 8, 9, 18]

[Guo-Yilong]

In the FUTR3D paper, you used radar coordinates, velocity measurements, and intensities.
In the comments of the code, they are " x y z rcs vx_comp vy_comp x_rms y_rms vx_rms vy_rms" .

I think 0->x ,1->y, 2->z,8->vx_comp,9->vy_comp,but I don't know the meaning of 18th dimension.
And how intensities are used?

I really appreciate for your help.
