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.
