Configuration item data list

Configuration item data list#

ECSS-E-ST-40C Rev.1 (with ECSS-Q-ST-80C for product assurance). This CIDL enumerates the configuration items of the Sentinel-2 MSI reverse-chain tool (s2_msi_raw_generator) deliverable. The tool reconstructs L1A -> L0plus -> Synthetic L0 by running a S2B L1B backwards through the exact inverse of the operational Synthetic L0->L1B radiometric chain (invert offset, relative-response/PRNU, dark, un-bin, SWIR re-stage, defective, crosstalk, on-board-eq; MTF-deconvolution OFF, so PSF and noise are not re-applied), validated against the reference ESA L0 img (10/20 m bands <=~4 DN).

Introduction#

The configuration items are the deliverable documentation, the online project files, and the software configuration items (the s2_msi_raw_generator package, its packaged calibration data, the scripts, and the tests). All items are version-controlled in the project git repository (gitlab.eopf ipf/s2-msi-raw-generator); the authoritative baseline is the main branch tip.
