These forks are used in conjunction with the Classic VRT Kit and the Basic Eclipse Kit to facilitate a VRT Solar Eclipse Raindrop and include the following weighted BORED forks:
BORED: 1 Low Saros 120.78hz, 1 Low Metonic 114.61hz, 1 Nodal 234.16hz
Use of this kit allows you to work with an Augmented 4th interval, plus many other options if you have the other Earth/Moon forks that are found in the other Planetary System Kits (New Synodic Moon, Earth Day, etc.)
