Some question about dataset

[lianchengmingjue]

Thanks for your impressive work.
I have some question about dataset in the onedrive link.
I guess:
10kmid.zip is LOGO-L
10khigh.zip is LOGO-H
10kgray.zip is LOGO-Gray
27kpng.zip is LOGO-30k
I wonder if this mapping is correct because there is some difference in naming.
Looking forward to your reply.
