Difference between the spectroscopic and seismic mass plotted as a function of spectroscopic mass for 157 unique high-luminosity stars with solar-like oscillations, plotted separately according to the spectroscopic parameters used. The seismic masses used in row (1) are the |$\mathrm{\nu }_{\mathrm{max}}$|-based seismic masses, in row (2) are the |$\mathrm{\Delta \nu }$|-based seismic masses, and in row (3) are the‘|$\mathrm{\nu }_{\mathrm{max}}$|  + |$\mathrm{\Delta \nu }$|’-based seismic masses. The blue squares use the spectroscopic masses and parameters by Jofré et al. (2015, 61 stars; column 1), and pink circles use those by Stock et al. (2018, 111 stars; column 2). Unfilled markers represent the stars with R > 30 R|$_\mathrm{\odot }$|⁠. The black dashed line indicates zero difference between the spectroscopic and seismic masses.
