  The pair correlation function of a strongly interacting one-dimensional
quantum dot is evaluated analytically within the framework of the spin coherent
Luttinger liquid model. The influence of electron interactions and temperature
on the competition between finite-size effects and electronic correlations is
analyzed, also in the regime of large numbers of particles. The development of
Wigner molecule correlations is observed as interactions get stronger. The
visibility of such signatures is enhanced for temperatures comparable with the
spin excitation energy of the system due to a suppression of the uncorrelated
Friedel contribution to the pair correlation function.
