Proper motion data for a reference star or fitted star.
Whether to just use these values or fit them is determined by the RefStar and FittedStar they belong to.
Units are radians/year Note: RA proper motion is pm_ra*cos(dec)

Apply proper motion correction to the input star, returning a star with PM-corrected coordinates.
NOTE: This method does not apply to the coordinate errors (Point does not include uncertainty).
star | The star to correct for this proper motion. |
timeDeltaYears | The difference in time from the correction epoch to correct for, in years. |
