Column density ratio of formamide to hot methanol. The red signs show the ALMAGAL sources, and the blue signs are the two low-mass sources, B1-c and S68N. The gray area shows the weighted standard deviation of log₁₀ of the data points around the weighted mean of log₁₀ of the data points (black solid line). The hot column densities for methanol are taken from Nazari et al. (2023b), and the column densities of formamide are taken from Nazari et al. (2021, 2022a). When focusing on methanol only at high temperatures closer to the sublimation temperature of formamide, the scatter is reduced.
