Some notes on the nearby (d=25.9pc) Sun-like star HIP 60370 = HD 107692 which currently has a single SIMBAD entry but appears to have 3 components in Gaia EDR3.
The Washington Double Star (WDS) catalog has entry WDS J12227-3911 (KPP 3034) for the pairing of the brightest and faintest of the components (labelled A and C below). The following values are quoted from Gaia EDR3, and the separation, PA, and delta(magnitude) is calculated using Gaia EDR3 values.
A: Gaia EDR3 6150200345317455232
RA = 185.68769743564 deg (+-0.0156 mas)
Dec = -39.17834193976 deg (+-0.0115 mas)
plx = 38.5703 (+-0.0217) mas
pmRA = 174.351 (+-0.017) mas/yr
pmDec = -148.523 (+-0.019) mas/yr
G = 6.56 mag
B: Gaia EDR3 6150200345317903616
RA = 185.68824750667 deg (+-0.1644 mas)
Dec = -39.17934984643 deg (+-0.0934 mas)
plx = 38.5146 (+-0.1818) mas
pmRA = 165.356 (+-0.210) mas/yr
pmDec = -118.961 (+-0.155) mas/yr
G = 15.45 mag
M_G = 13.38 mag (consistent with mid-M dwarf)
AB pair:
sep = 3939.81+-0.19 mas (3.94")
PA = 157.07 deg
delta(G) = 8.89 mag
C: Gaia EDR3 6150200345317455872
RA = 185.68483595146 deg (+-0.2399 mas) ICRS,ep.2016.0
Dec = -39.17392714851 deg (+-0.1871 mas)
plx = 38.5047 (+-0.3433) mas
pmRA = 171.664 (+-0.290) mas/yr
pmDec = -152.112 (+-0.449) mas/yr
G = 18.80 mag
M_G = 16.73 mag (consistent with late M or early L dwarf)
AC pair (KPP3034):
sep = 17786.69+-0.30 mas (17.79")
PA = 333.32 deg
delta(G) = 12.25 mag
