Median magnitude vs. MAD in the WISE1 (left) and WISE2 (right) bands. For the WISE1 band, the differences of median values of MAD between the SMC and LMC are about −0.0050 (brighter sources; ≤ − 10.0 mag shown as the vertical dashed line), −0.0012 mag (fainter sources; >  − 10.0 mag), and −0.0045 mag (all sources). For WISE2 band, the differences are about 0.0012 (brighter sources), −0.0008 (fainter sources), and −0.0035 mag (all sources), respectively.
