| Description: This attribute describes the rotation angle around the spacecraft +Z-axis from the spacecraft attitude after the rotation around the spacecraft +Y-axis of the value of the first_rotation_angle_for_stray_light attribute from the reference spacecraft attitude which has the spacecraft +Z-axis is same as the Sun-direction vector. This angle is utilized to define the magnitude of the radiator stray light in the ONC-T image. When the value of the second_rotation_angle_for_stray_light attribute is larger than -7 degrees and the value of the first_rotation_angle_for_stray_light attribute is smaller than -5 degrees, the radiator stray light in the ONC-T image exceeds 1 count per second. |
