Abundance ratio of NH2CHO and HNCO with respect to CH3OH against source luminosity. Red points show the results for the sources considered in this work. The grey points indicate other low- and high-mass sources. These sources are IRAS 16293A (Ligterink et al. 2017; Manigand et al. 2020), IRAS 16293B (Coutens et al. 2016; Ligterink et al. 2017; Jørgensen et al. 2018), HH 212 (Lee et al. 2019), AFGL 4176 (Bøgelund et al. 2019a), and NGC6334 MM1 and MM2 (Bøgelund et al. 2019b).
