The SLUGGS survey: Using extended stellar kinematics to disentangle the
  formation histories of low mass S0 galaxies
  We utilise the DEIMOS instrument on the Keck telescope to measure the
wide-field stellar kinematics of early-type galaxies as part of the SAGES
Legacy Unifying Globulars and GalaxieS (SLUGGS) survey. In this paper, we focus
on some of the lowest stellar mass lenticular galaxies within this survey,
namely NGC 2549, NGC 4474, NGC 4459 and NGC 7457, performing detailed kinematic
analyses out to large radial distances of $\sim 2-3$ effective radii. For NGC
2549, we present the first analysis of data taken with the SuperSKiMS (Stellar
Kinematics from Multiple Slits) technique.
  To better probe kinematic variations in the outskirts of the SLUGGS galaxies,
we have defined a local measure of stellar spin. We use this parameter and
identify a clear separation in the radial behaviour of stellar spin between
lenticular and elliptical galaxies, thereby reinforcing the physically
meaningful nature of their morphological classifications.
  We compare the kinematic properties of our galaxies with those from various
simulated galaxies to extract plausible formation scenarios. By doing this for
multiple simulations, we assess the consistency of the theoretical results.
Comparisons to binary merger simulations show that low-mass lenticular galaxies
generally resemble the spiral progenitors more than the merger remnants
themselves, an indication that these galaxies are not formed through merger
events. We find, however, that recent mergers cannot be ruled out for some
lenticular galaxies.
