These values are obtained summing all the processing times associated to theelementary processing steps implemented to generate a product of Level-1A, 1B or 1C. Inthe last row of the table the estimated time of a production up to Level-1C with intermediaryproducts (1A and 1B) compressed in JP2K and delivered; the time necessary for theJPEG2000 compression is then considered three times.ESA UNCLASSIFIED – For Official Use© ESAThe copyright of this document is the property of ESA.
