Wrong metadata reading

With sample SAR data (.h5 file), it seems radar frequency is missing from metadata.

  • Abstracted metadata - radar_frequency = 99999.0

But when I check .xml file, radar frequency is another value.
xxxxxxxxxxx - it’s not 99990000000.

  1. Is there any reason that SNAP didn’t read radar frequency?
  2. Can I edit metadata on SNAP?

what sample data are you using?
Please provide a link in case it is available online so we can test.
