Representative 1D profiles of rms slopes of the AFM (panel (a)), ALSCC (panel (b)), PCAM (panel (c)), LCAM (panel (d)), NAC (panel (e)), and SLDEM (panel (f)) ROIs with azimuth angles of 0° (green), 45° (yellow), 90° (blue), and 135° (red). In panel (b), the effective slope (20°–35°) inverted by the Diviner TIR data is indicated by the horizontal gray shaded area, and the spatial scales that satisfy the TIR-sensitive slope are denoted by the vertical solid lines.
