Sgr A* Semimajor axis in mpc was converted to arcseconds based on a quoted Eck2002
distance of 8 kpc. Errors for Eck2002 orbits are as follows: Sel2002

Note: This system has grown more complex as additional stars orbiting
the Galactic Center have been observed. With the number of companions
now exceeding 170, it has become increasingly difficult to maintain
the usual WDS designation/component scheme. All WDS pairs were
therefore copied to the WDSS (WDS supplemental catalog) in July 2017;
henceforth the standard published designations for Sgr A* companions
will be used for all components.
