Azimuth Sentinel 1

Hello,

I work with Sentinel 1 data from Google Earth Engine or Sinergise (via Mundi Web Services). I work in Python.

I need azimuth data which neither of them provide. Google Earth Engine provides orbit number which presumably could be used to calculate azimuth (?).

This is the metadata that GEE provide:

Does anyone know where I could find information on orbital number angle (or how to get azimuth from the metadata they offer).

Many thanks,
Tatiana
