Left panels: the metallicity profile for NGC 4254 from Skillman et al. (1996) using the published Z94-based metallicities (blue circles) and converted into the PP04 O3N2 base calibration (red circles). The black dashed line marks the assumed stripping radius at R/R_E < 1.5. Right panels: the two limits for NGC 4254 (black triangle) plotted on the M-Z diagram are based on the integrated metallicities for the total profile and for R/R_E < 1.5 i.e. “before” and “after” gas-stripping. The galaxy is shifted from the total M-Z relation (solid black line) to the best fit relation (dashed black line) to the Hi deficient galaxies (red circles).
