 C_{
x
} and C_{
y
} are the center of the field of view (in unit of pixel); A_{rot} is field rotation angle (degree); R_{
f
} is focal length ratio (%); Res is fitting residual (pixel); and + Y is spacecraft direction, where 1 pixel = 0.0117°. “Initial guess” means the expected parameter value for exact camera setting
