What the means of a in x, y, w, h, a = ann['bbox']

[fuqianya]

Hi,

Thanks for your great work! I have a question regarding the variable a in x, y, w, h, a = ann['bbox']. Could you please clarify what a represents?

Additionally, could you kindly release the annotations/val_mod_illumination.json file?

Thank you!
