discov_num	notes	refcode
RST4917	1995.1024: Quadrant determined by speckle imaging analysis.	Hor1996
	1997.1229: A smaller annulus was used in the power spectrum fit due to
	the faintness of the source. As a consequence, the separation and
	position angle uncertainties may be larger than other measures.	Hor1997
