The addition of QUIJOTE-MFI data significantly improves the parameter estimation of the low-frequency foregrounds, especially the estimation of the synchrotron spectral index, $\\beta_s$. We present the first detailed $\\beta_s$ map of the Northern Celestial Hemisphere at a smoothing scale of $2^{\\circ}$.
