Popis:	The J-region Asymptotic Giant Branch (JAGB) method is a standard candle based on the intrinsic luminosities of carbon stars in the near infrared. We directly constrain the impact of metallicity, age, and reddening on the JAGB method. We assess how the mode, skew, and spread of the JAGB star luminosity function change throughout diverse stellar environments in M31's NE disk from 13Comment: 16 pages, 10 figures, 1 table, accepted to ApJ
