Question about alignment between colmap and ROMP

[LarkLeeOnePiece]

what's the meaning of "smpl_optimized_aligned_scale.npz" for each dataset? Since the SMPL parameters from ROMP are in the camera space, if we want to render the image using the camera of colmap. It means we need to align the coordination between them. Does this file mean the pose and translation of the human has been aligned into the colmap world coordination?
