Summary of the results when having R0, hR and hσ as free parameters and adopting different distance estimates.
| Distance estimate | Slope (first 2 bins removed) [km s−1 kpc−1] | ρ0 [GeV cm−3] | MDM(R < 14 kpc) [M⊙] | VLSR [km s−1] |

7 ± 7 |
| BJ21 + ϖ/σϖ > 10 | −0.3 ± 0.3 (−1.0 ± 0.3) |

| GSP-Phot + ϖ/σϖ > 10 | 0.6 ± 0.3 (0.2 ± 0.3) |

| GSP-Phot + ϖ/σϖ > 20 | 0.4 ± 0.6 (−1.1 ± 0.3) |

Notes. Namely, photogeo distances from Bailer-Jones et al. (2021) with a cut in parallax of ϖ/σϖ > 5 and ϖ/σϖ > 10, and GSP-Phot distances with quality parallax cuts of ϖ/σϖ > 10 and ϖ/σϖ > 20 (fiducial case). The second column shows the estimated slope of the circular velocity curve when a straight line is fitted to all bins (and in brackets the value obtained by eliminating the first two radial bins as the circular velocities increase within ∼5 − 7 kpc), the local DM density and DM mass within 14 kpc are shown in the third and forth columns, respectively. We quote the velocity of the LSR in the last column.
