Although the standard cosmological model, the so-called Λ cold dark matter (ΛCDM), appears to fit well observations at the cosmological level, it is well known that it possesses several inconsistencies at the galactic scales. In order to address the problems of the ΛCDM on a small scale, some alternative models have been proposed. Among the most popular candidates, the proposal that dark matter in the universe is made of ultralight bosons is a strong candidate today. For this work, we study through an analytical approach the consequences arising from comparing the Spitzer Photometry and Accurate Rotation Curves catalog observed-baryon acceleration correlation with the scalar field dark matter model. We carry out such analysis either considering the features of galactic halos extracted from structure-formation simulations or considering the existence of other non-dark-matter elements in the whole system (such as baryons or a supermassive black hole). Specifically, we address a recent claim that the model is not capable of reproducing a constant surface density in the core, in contrast to what observations suggest for a host of galaxies with different sizes and morphologies. In this direction, we show that this discrepancy can be alleviated once the contributions of non-dark-matter constituents in the whole galactic system are taken into account. Additionally, we find that a mass of m ≃ 1.41 x 10^–22 eV/c² is capable of reproducing all of our findings and correctly adjusting the rotation curves coming from the Milky Way galaxy.
