Introduction of constellation phase

Phase is the angle between two planets and the center of the astrolabe. For example, the sun, the moon and the center of the astrolabe are connected in a line, and the angle between the two lines is the phase. When the phase is good, even if the planet falls into the constellation, the parties can turn the tide. If the phase is not good and the constellation of the planet is not good, other planets and phases should be used to remedy it.
