      abstract     = {The pixel detector of the Belle II experiment is based on
                      the DEPFET technology. Fora reliable readout, it is
                      essential to determine the pedestal (baseline current) of
                      each pixel.This work focuses on characterizing the pedestal
                      measurements and their development overtime. For this
                      purpose, data over a period of two months was analyzed for
                      fluctuations overseconds and the formation of geometric
                      structures.While most pixels exhibit negligible fluctuations
                      over short time periods, some show discrete jumps in the
                      pedestal values. Structures in rows, columns and in edge
                      regions can beobserved. Most notably the ’double row
                      effect’, which highlights a behavioral differencebetween
                      adjacent double rows, stands out in the development over
                      time. This effect resultsin divergent pedestal values that,
                      if left unaddressed, could affect the detector’s
                      efficiency.Therefore, further investigation of the ’double
                      row effect’ is needed, particularly in light ofany damage
                      that may have occurred to the detector.},
