What it is cited for
Where an entry recorded why it leaned on this work, the reason is repeated here. A source cited well outside its own scope is visible in this list before it is visible anywhere else.
- Cross-Quarter Days
- For the solar-longitude search that yields the astronomical midpoints.
- Heliacal Risings
- For the positional astronomy the visibility criterion is layered onto.
- Precession of the Equinoxes
- For the modern constants and for the distinction between the year lengths.
- Solstices and Equinoxes
- For the definition by apparent geocentric solar longitude and for the computation of the instants.
- The Chinese Lunisolar Calendar
- For the non-uniform apparent motion of the sun, which is why an angular midpoint and a temporal midpoint are different instants.
