discov_num	notes	refcode
STF1831	D. Arnold noted considerable overlap of measures for the two multiple	Arn2004a
	systems STF1831 and 14157+5640STF1830, with STF1831CE = STF1830DA and
	STF1831EF = STF1830AB. They have therefore been combined into one WDS
	system, maintaining the WDS and most of the component designations for
	STF1831. Designation changes are as follows:
	STF1830AB --> STF1830EF
	STF1830AC --> STF1830EG
	STF1830AD --> STF1830CE (with quadrant flip)
	STF1831CE --> STF1830CE
	STF1831EF --> STF1830EF.
	Finally, the single measures of AD and CD were misidentified, so these
	measures were reassigned to the proper components.
