| contents | The flat spectrum radio quasar PKS 1510-089 is one of the most active blazars across the entire electromagnetic spectrum, displaying periods of flaring activity. This study explores its spectral variability over a decade. By employing the non-thermal dominance parameter, we analyze the H$β$ and $\lambda5100\text{ Å}$ continuum light curves, as well as the full width at half maximum of the H$β$ emission line, to identify whether the primary source of the continuum emission is the accretion disk or the jet during activity periods. Our results shows an anti-correlation between the full width at half maximum and the luminosity of the H$β$ emission line across all datasets. This indicates, that variations in H$β$ luminosity consistently reflects the canonical broad-line region, irrespective of whether the primary ionizing source is the accretion disk or the jet. The anti-correlation persisted when comparing the full width at half maximum of H$β$ against the luminosity at $\lambda5100\text{ Å}$ in the disk dominance regime. These findings, along with the observation that flaring events in the $\lambda5100\text{ Å}$ continuum, attributed to the jet, coincide with flares in the H$β$ emission line, suggest that the base of the jet is located within the broad-line region. Based on the 219 spectra within the disk dominance regime, we estimated a mean black hole mass of $M_{BH}=2.85\pm0.37\times10^{8}\: M_{\odot}$. |
