Same as Fig. 5, but for (a) the R value calculated from the SHARP B_r and B_LOS components (black and purple crosses) and from the collated dataset (red diamonds), and (b)–(d) the total length of MPILs, the length of the main MPIL, and the magnetic flux associated with MPILs, calculated from the SHARP B_LOS and the collated SDO/HMI – SO/PHI-FDT dataset (purple crosses and red diamonds, respectively). Dashed lines mark the first day of each month, to facilitate a comparison.
