Minimize Missing in-flight average bad pixel mask

Along the entire mission, 1436 Level 1b consolidated products were generated without updated in-flight average dead and bad pixel mask (DBPM) as measurements in the previous days result too sparse. DBPM calculation in fact uses individual masks for the last seven days (around 100 orbits) to calculate a smoothed average mask. For these orbits, DBPM from a reference auxiliary file was used.
