Description

MoonSeparationConstraint does not check if moon is up (similar to MoonIlluminationConstraint), so this constraint holds even when moon is down. The same moon_up_mask/moon_down_mask from MoonIlluminationConstraint should appear there.

Research direction

Start by locating MoonSeparationConstraint and MoonIlluminationConstraint, then compare how moon_up_mask and moon_down_mask are obtained and applied. The work is done when MoonSeparationConstraint does not hold while the Moon is down and its behavior matches the corresponding illumination constraint cases.
