Could be 1D histograms showing predicted and measured values? Maybe better to show PMa, rather than absolute astrometry.

We need some way to recognize different instruments.

there's only a few things left from the XYZ cartesian basis left to move (or possibly not move and close?).

@chihchunhsu can you check if the most recent updates to orbitize fix this? we just merged in a bugfix for this onto the main branch

Is this the most recent version on pip, or did you directly pull the most recent changes on the main branch? We have yet to formally release this version.

Mainly just for stellar astrometry. Only matters for nearby stars.

Related to #326 but more about absolute astrometry/spherical geometry.

Just for planet RVs. No rush in implementing -- do it when we need it.

Essentially a different basis that makes the orbits linear in 4 parameters (analytical marginalization). Would need new basis class + new chi2 function for analytical marginalization of orbital elements.

Would be interesting to check if integration time matters also. Also BJD/HJD differences?
