Comparison of the two mass-averaged temperature estimates made for the 151 luminous protostellar cores of ALMA-IMF bright enough to be detected in the luminosity maps. (a) Fractional difference between estimates from the protostellar core luminosity (Col. 5 of Tables C.4 and C.8 published at the CDS) and the background-diluted temperature of cores (Col. 6 of Tables C.4 and C.8 published at the CDS). Protostellar cores in Young, Intermediate, and Evolved protoclusters are indicated by green circles, orange diamonds, and red stars, respectively. The black line shows that the median fractional difference between these two estimates is ~36%. (b) Distribution of the differences between the two temperature estimates of Cols. 5–6 in Tables C.4 and C.8 published at the CDS (blue histogram). Colored dashed lines locate the median of the differences: ~19 K in Young and Evolved protoclusters (green and red, respectively) and ~26 K in Intermediate protoclusters (orange).
