Redetermined stellar parameters and physical quantities of HIP 41484.

Sp 		G5V Spectral type
$T_{\rm eff}^{\rm std}$ (K) 5864 Effective temperature
$\log g^{\rm std}$ (cm s-2) 4.33 Surface gravity
$v_{\rm t}^{\rm std}$ (km s-1) 0.92 Microturbulence
{Fe/H} +0.05 Metallicity ( $\equiv A_{\rm Fe} - 7.50$)
V 6.32 Apparent visual magnitude
p (mas) 45.89 ($\pm $0.84) Hipparcos parallax
MV 4.63 Absolute visual magnitude
B.C. -0.12 Bolometric correction
$M_{\rm bol}$ 4.51 Absolute bolometric magnitude
$\log (L/L_{\rm sun})$ 0.096 Bolometric luminosity
$M_{\rm iso}/M_{\rm sun}$ $\rm 1.06^{+0.04}_{-0.03}$ Mass (from tracks)
$\log age_{\rm iso}$ (yr) $\rm 9.37^{+0.29}_{-0.40}$ Age (from tracks)
$M_{\rm iso}/M_{\rm sun}$ $\rm 1.05^{+0.05}_{-0.05}$ Mass (from isochrones)
$\log age_{\rm iso}$ (yr) $\rm 9.54^{+0.32}_{-0.34}$ Age (from isochrones)
$\Delta T_{\rm eff}$ (K) +87.6 Star-Sun $T_{\rm eff}$
$\Delta \log g$ (cm s-2) -0.036 Star-Sun $\log g$
$\Delta v_{\rm t}$ (km s-1) -0.10 Star-Sun $v_{\rm t}$
$\Delta${Fe/H} +0.060 Star-Sun metallicity ([Fe/H])
$V_{\rm hel}$ (km s-1) -32.3 Heliocentric radial velocity
$\langle R_{\rm m} \rangle$ (kpc) 7.337 Mean galactocentric distance
e 0.136 Orbital eccentricity
$z_{\rm max}$ (kpc) 0.172 Max. separation from galactic plane
$U_{\rm lsr}$ (km s-1) +30.5 Space velocity (radial)
$V_{\rm lsr}$ (km s-1) -23.4 Space velocity (tangential)
$W_{\rm lsr}$ (km s-1) -15.2 Space velocity (vertical)
EW(6708) (m$\rm\AA$) 11.0 Equivalent width of Li  I 6708
$A_{\rm Li}$(NLTE) 1.73 Non-LTE Li abundance
$\Delta_{\rm NLTE}$ +0.06 Non-LTE correction
$v_{\rm r+m}$ (km s-1) 2.90 Macrobroadening velocity
$v_{\rm e} \sin i$ (km s-1) 2.64 Projected rotational velocity

Notes. These are the revised parameters of HIP 41484 established based on the new spectrum data for this star, since the values of spectroscopically determined quantities (e.g., atmospheric as well as line-broadening parameters, radial velocity, and Li abundance) for this star reported in Paper I turned out to be erroneous because a wrong spectrum (actually that of HIP 41184) was used. See Paper I for more details of the meanings of these quantities and the procedures for their determinations.
