Question about the band index

[Mohouwa]

Hello!

I noticed in your study that the index range for Sentinel-2 data is from 1 to 13. However, according to the GEE documentation (https://developers.google.com/earth-engine/datasets/catalog/COPERNICUS_S2_SR_HARMONIZED), the Level-2A bands are labeled B1 to B8, B8A, B9, B11, and B12, which only include 12 bands and omit B10. In your code, it appears that band index 10 is skipped during the data preprocessing phase, and you work with 13 bands. Could you clarify if B8A corresponds to index 9 in your study? Does index 10 refer to B9? Also, I would like to know if index 13 in your study corresponds to the Aerosol Optical Thickness (AOT)?

Thank you for your attention to these questions！
