product /home/datawork-cersat-public/project/mpc-sentinel1/data/esa/sentinel-1a/L1/IW/S1A_IW_GRDH_1S/2021/001/S1A_IW_GRDH_1SDV_20210101T213015_20210101T213040_035950_043604_0184.SAFE seems to have duplicate values in azimuthTime Doppler annotations. When trying to do a xsar.open_dataset() it crashed:

...
649 ds['geometryDcPolynomial'] = xr.DataArray([Polynomial(p) for p in dc_geoDcPoly], dims=['azimuthTime'],attrs={'source':xpath_mappings['annotation']['dc_geoDcPoly'][1]})
...
ValueError: cannot reindex or align along dimension 'azimuthTime' because the (pandas) index has duplicate values
