Difference maps between the interband time delays determined in the present work and calculated according to Eqs. (2) and (10). The brightest regions correspond to the smallest difference between these values. The maps are built for three black hole masses, from top to bottom: MBH = 2 × 108 M⊙, MBH = 9 × 108 M⊙, and MBH = 20 × 108 M⊙.
