Wesenheit relations for F150W for Figure 9. Additional hosts and color combination relations may be found in A. G. Riess et al. (2024a). F150W data are from GO programs 1685 and 2875 (PI: A. Riess), with the exception of NGC 4038 and M101, and all F555W − F814 colors are from the HST SH0ES project. All data are phase-corrected using an additional JWST short-wavelength color as described in Section 3.2.1.
