Comparison of velocity dispersion measurements for the JWST/NIRSpec spectra for RXJ1131−1231. The differences in the measured dispersions are averaged over 21 spaxels within a 0$\stackrel{″}{.}$5×0$\stackrel{″}{.}$5 square at the center of the lens galaxy. This figure is in the same format as Figure 10, except that fewer libraries are shown, only the ones that include the wavelength region of the Ca II triplet used to fit the JWST/NIRSpec data.
