^(a)

Notes.PA offset with respect to the MSA shutter. 0° corresponds to the major-axis alignment, 90° corresponds to the minor-axis alignment.

^(b)

Stellar masses for a Chabrier (2003) IMF from Slob et al. (2024).

^(c)

Galaxies without COSMOS-Web coverage. The structural parameters are taken from HST/ACS F814W imaging (Scoville et al. 2007; Griffith et al. 2012).

^(d)

Galaxies for which we cannot constrain the rotational velocity. We report 2σ lower limits for V_{r_e}, V_{r_e}/σ₀, and λ_{r_e}.
