Temperature, mass and luminosity of the seven clumps identified in HGL23.271-0.263, six protostellar and one starless. Columns 1 and 2: IRDC name and source number. Column 3: protostellar or starless type. Columns 4–6: radius, mass and luminosity of each source. Columns 7 and 8: temperature and the associated error estimated with the mpfit routine. Column 9: χ2 value of the greybody fit. Column 10: source distance, equal to the parent IRDC distance.
