Abstract:
We present spectroscopic stellar parameters for the complete target
list of 164 evolved stars from the Pan-Pacific Planet Search, a
five-year radial velocity campaign using the 3.9m Anglo-Australian
Telescope. For 87 of these bright giants, our work represents the
first determination of their fundamental parameters. Our results carry
typical uncertainties of 100K, 0.15dex, and 0.1dex in Teff, logg,
and [Fe/H] and are consistent with literature values where available.
The derived stellar masses have a mean of 1.31-0.25+0.28M☉,
with a tail extending to ∼2M☉, consistent with the
interpretation of these targets as "retired" A-F type stars.
Description:
The Pan-Pacific Planet Search (PPPS) operated at the 3.9m
Anglo-Australian Telescope (AAT) from 2009 to 2014, targeting 164
southern hemisphere evolved stars (see Paper I, Wittenmyer et al.
2011, Cat. J/ApJ/743/184).
All observations were carried out at the AAT using its UCLES echelle
spectrograph. The PPPS program uses the Doppler technique for
measuring precise radial velocities, with an iodine absorption cell to
calibrate the spectrograph point-spread function. An iodine-free
"template" observation is acquired for each target at a resolution
R∼60000 and a signal-to-noise of 100-300pixel-1. In this work, we
use the iodine-free templates to determine spectroscopic stellar
atmospheric parameters.

Note (1): Using the empirical calibration relations from Alonso et al.
(1999A&AS..140..261A 1999A&AS..140..261A). The B, V, and K color indices were obtained from the
SIMBAD database. See Section3.2 for additional details.
Note (2): The surface gravity was estimated with the method described by Liu et
al. (2007, Cat. J/MNRAS/382/553; 2012, Cat. J/MNRAS/422/2969) with the
equations (1), (2), and (3) in the paper (see Section3.2).
Note (3): The InfraRed Flux Method IRFM is arguably one of the most direct and
least model dependent techniques to determine effective temperatures in
stars (e.g., Blackwell & Shallis, 1977MNRAS.180..177B 1977MNRAS.180..177B; Blackwell et al.,
1979MNRAS.186..633B 1979MNRAS.186..633B, 1980MNRAS.191..445B 1980MNRAS.191..445B). Our analysis is based on the
IRFM described in Casagrande et al. (2010, Cat. J/A+A/512/A54;
2014MNRAS.439.2060C 2014MNRAS.439.2060C). See Section3.3 for further details.

Note (4):
We adopted the reddening estimation according to Schlegel et al.
(1998ApJ...500..525S 1998ApJ...500..525S) with the corrections stated by Arce & Goodman
(1999ApJ...512L.135A 1999ApJ...512L.135A) and Beers et al. (2002AJ....124..931B 2002AJ....124..931B) to obtain the
color excess E(B-V)A. For nearby stars, the reddening value is calculated
as:
E(B-V)=[1-exp(-|Dsinb|/125)]E(B-V)A,
where D is the distance of the star and b is the Galactic latitude, both
were obtained from the SIMBAD database.
Note (5): We adopted E(V-K)=2.948E(B-V) as the color excess for (V-K) (Schlegel
et al., 1998ApJ...500..525S 1998ApJ...500..525S).
