What do the values in gt.txt represent

[YuTingShi123]

Thanks for your great work! I would like to use your dataset to train and test my tracking model, but it is currently unclear what the values in each row of gt.txt in the dataset specifically refer to? (For example: 1,1582,24,6,9,1, -1, -1, -1) Can you give a brief introduction? Or where is there an explanation?
