Question about the pred_tracks units and ranges

[skygoo2000]

Hi! Yuxi,

Thanks a lot for releasing the code and model for this awesome project! I learned a lot from this code. However, I am still a little confused about the pred_tracks, especially for the range. I found that there is a huge discrepancy in z-values between different samples. I will be grateful if you can point out the range and units of the pred_tracks z -z-values (just like x and y)
