Notes. (a) Reference F19 claims that 1994ae used the version of the light curve from Riess et al. (2005), but C. Burns, who performed the fit, sourced the data from the Open Source Catalogue, which instead used Riess et al. (1999). We further confirm that the value in Uddin et al. (2024) matches Riess et al. (1999), not Riess et al. (2005)
