  We report a high-resolution laser-based angle-resolved photoemission
spectroscopy (laser-ARPES) study of single crystals of FeSe, focusing on the
temperature-dependence of the hole-like bands around the ${\rm \Gamma}$ point.
As the system cools through the tetragonal-orthorhombic "nematic" structural
transition at 90~K, the splitting of the $d_{xz}$/$d_{yz}$ bands is observed to
increase by a magnitude of 13 meV. Moreover, the onset of a $\sim$10 meV
downward shift of the $d_{xy}$ band is also at 90~K. These measurements provide
clarity on the nature, magnitude and temperature-dependence of the band shifts
at the ${\rm \Gamma}$ point in the nematic phase of FeSe.
