Mass estimates for ACTJ0240 in literature, compared to this work. The median mass estimate and the corresponding 16th and 84th percentile errors from this work are shown using the magenta-star marker. Square-orange markers represent the mass values estimated from the Compton parameter-mass scaling relations for different pressure profile (PP) models mentioned in the plot (references: H13; A10; Bode et al. 2012; Trac et al. 2011; Sifón et al. 2013; Hilton et al. 2021). Lime-diamond markers are the optical mass proxies calibrated through various sources mentioned in Hilton et al. (2021) and Wen & Han (2015).
