I suspect that the 3-D rectangular origin (0, 0, 0) in
rectangular coordinates is or is near the centre of
mass (barycentre) of the solar system.

The ecliptic is a reference plane that approximates
very well the mean orbit of the earth around the sun.

I sincerely doubt that people in solar dynamics would use
an ecliptic reference plane where the sun would move
at 220 km/sec .

In the old days, the proper motions of extra-solar stars
relative to the earth were not known.

Wikipedia quote:

<< The Sun travels in a nearly circular orbit (the solar circle) about
the center of the Milky Way at a speed of about 220 km/s at a radius of
8 ± 0.65 kpc from the center,[4][5] which can be taken as the rate of
rotation of the Milky Way itself at this radius.[6][7] >>
