Radial surface-brightness profiles of NGVS 3543 measured in eight bands, shown as blue filled dots. The surface brightness units are in mag arcsec⁻² for all the bands except for Hα which is in erg s⁻¹ cm⁻² arcsec⁻². The blue shaded area marks the 1σ error (for data points) and upper-limits (3σ). The black dotted line indicates the best-fit model described in Sect. 3.1 for a ram-pressure stripped galaxy ( km s⁻¹, and t_rps = 13.4 ± 0.1 Gyr). The green dot-dashed line shows the same model for an unperturbed system. The red shaded area shows the range of models allowed for the same spin and velocity, but allowing variation in the RPS efficiency and FWHM parameters as discussed in Sect. 3.1. The vertical red dotted line gives our measured g-band effective radius of the galaxy.
