Difference between two images with the same date in names

Hi, dear all, we have two images with almost same names (S1A_IW_GRDH_1SDV_20160128T034716_20160128T034741_009689_00E22E_B0E2 and S1A_IW_GRDH_1SDV_20160128T034716_20160128T034741_009689_00E22E_D1E0). We used the data from the scihub. These images have different ingestion date (2016-01-28T07:41:05.572Z and 2016-06-22T16:35:27.194Z ). The problem is that they have different cycle number (71 and 69) but the same sensing start time and slightly different sensing stop time (1 sec difference). After some computations we get different values of sigma (after terrain correction). Which of two images is reliable?

Hi Veronika,

maybe it is better to ask the support of the scihub.
You can contact them by email: eosupport@copernicus.esa.int

Thank you! I will try to contact them.
