The definition of xxx.yy.zz version is the following: xxx : baseline collection (starting from 002, 003 or 004 depending on the chain) yy : minor changes in IPF or in static ADF (starting from zero for new baseline collection) zz: changes in L0/PUG processing/task tables/PM or any other changes not expected to affect the quality of the products (starting from zero when new baseline collection or minor change is introduced). Only one PB_ID is applied on OLCI L1: e.g. in case of change of RAC or SPC IPF which has no significant impact on product quality, zz shall be incremented.
