Question about pixel size parameter in the dataset

[jiahaooo]

Hi maintainers,

Thank you for creating and maintaining this valuable dataset! I'm currently working with the image data and would like to better understand the spatial scale relationship.

Could you kindly clarify the physical scale parameter (pixel size) of the images? Specifically, how many micrometers (µm) does a single pixel in the dataset represent in the physical world? If this parameter is documented in any publications or technical specifications, or publications, I would greatly appreciate it if you could point me to the relevant reference.

Thank you for your time and assistance. Looking forward to your guidance!

Best regards,
