The meaning of the vector of a pose in HumanML3D and KIT-ML.

[HitBadTrap]

Hi! I'm confused about what each dimension of the 263-dimension vector of a pose in HumanML3D and the 251-dimension vector of a pose in KIT-ML represent(e.g., which dimensions represent the head and foot, etc.). Could you provide detailed information or relevant links?

Thanks.
