  • new function S1_NRB.metadata.extract.calc_enl to calculate ENL for linear-scaled backscatter images
  • new product metadata fields in both OGC XML (equivalentNumberOfLooks) and STAC (sar:looks_equivalent_number) storing the median ENL value calculated from 25x25 windows over the cross-pol, linear backscatter image (-(vh|hv)-[gs]-lin.tif)
  • new page in documentation including infos on ENL calculation in metadata, how to use calc_enl to calculate ENL arrays from backscatter images and a comparison between GRDH and SLC-derived S1-NRB products

Sorry for the back and forth commits to fix the figures. Oxygen and concentration levels are running low here 😅 and for some reason some small details (e.g., space after figure) looked different in my local sphinx build.
