Greetings Stulli and EfilOne (and anyone else with an opinon on meridian systems)
I am somewhat in doubt which systems should be registered as the Meridian, but here are some thoughts:
1) I think we should use
Sol as the reference point to determine meridian systems (and not Sag A*), since Sol is the origo for the galactic grid and galactic coordinates. Current eastern and western meridian is placed based on the grid, and not on Sag A*. A meridian is a human imaginary construct, just like the galactic coordinates, so it makes sense to me to have those based on Sol as the common reference point.
(Other questions, such as measuring the size of the galaxy might well take Sag A* into account though...)
2) A meridian system should be the one closest to the zero-line of Sol among thoses systems "most distant from Sol". I admit that it is a somewhat ambigous definition.
If we go with this definition and look at the candidates for southern meridian.
- Borchgrevink Point (current southern meridian): Coordinates: 25.03125 / -16.875 / -15461.9375 => dist to zero-line = 30.19 LY
- Hypuae Euq ZK-P d5-0: Coordinates: 24.84375 / -16.96875 / -15940.15625 => dist to zero-line = 30.09 LY
- Livingstone Point: Coordinates: 101.5625 / -22.46875 / -16097.09375 => dist to zero-line = 104.02 LY
It looks to me like Hypuae Euq ZK-P d5-0 should be made the southern meridian on the merit of being closest to the zero-line of Sol, and also 500 LY further out than the current southern meridian system.
But Livingstone Point should definitely be registered as noteworthy system in its own right.
