Dear friends
I was downloading some data and I saw two same data with difference product unique number.
S1A_IW_SLC__1SDV_20150113T044810_20150113T044838_004148_005074_2139
S1A_IW_SLC__1SDV_20150113T044810_20150113T044838_004148_005074_60D8

The product unique identifier (CCCC) is a hexadecimal string generated by computing CRC-16 on the manifest file using CRC-CCITT.
I can not understand what is the meaning with these differences?

The same data-take has been processed into a product more than once. Metadata should indicate processing time and processor version etc.
