Notes. The MWNSC is aligned with respect to GP.

(a)

Fits to the symmetrized images that we create by assuming symmetry of the NSC with respect to the GP and with respect to the Galactic north–south axis through Sgr A*.

(b)

Stellar number density for the NSD at its effective radius.

(c)

Stellar number density for the NSC at the effective radius Re.

(d)

The flattening q is equal to the minor axis divided by the major axis.

(e)

n is the Sérsic index.

(f)

Re is the effective radius for the NSC.
