a Top left. Comparison between LIDAR topography and maximum, minimum, and average topography in the simulated field of view of the LIDAR estimated from shape model in the green circle. btop right. Whole view of the ONC-T image taken 07h52m08s on July 20, 2018 at altitude of 6.4 km from the surface. The area in the red frame corresponds to the area shown in (c). c bottom right. Enlarged ONC-T image of (b). Black and green circle are estimated LIDAR receiving telescope field of view from Matsumoto et al (2020) and this study, respectively. d bottom left. Simulated topographic map from the shape model with the same viewing angle as (c). Meaning of the two circles are the same as (c). (Image list: hyb2_onc_20180720_075208_tvf_l2a.fit)
