Orbit depending STAC search for Sentinel-1 data

[sebfoe]

It can be useful sorting Sentinel-1 SAR acquisitions by orbit, i.e. ascending or descending. To avoid possible struggle I will post a solution here.
Passing query = {"sat:orbit_state": {"eq": "descending"}}

to

catalog.search( collections=["sentinel-1-grd"], bbox=bbox_of_interest, datetime=time_of_interest, query=query)

should do the job. Pitfalls I had were trying to set a "properties" level prior to "sat:orbit_state"and using "descending" instead of {"eq":"descending"}.

Best,
Sebastian
