One civil year of apparent geocentric tropical longitudes at Greenwich 0h UT, computed on demand by the running Moira engine and read as adjacent midnight rows. The plate records the engine and kernel actually used.
A whole year on your desk.
Generate a civil year to reveal its daily positions. Start with two adjacent midnight rows and carry their difference into your paper working.
