Notes. (2a)–(2c) Name, RA and Dec coordinates of the four locations around which the luminosity profiles, presented in Fig. D.2, are built to characterize the six brightest methyl formate (MF) sources of the ALMA-IMF survey (Bonfand et al. 2024), encompassing eight protostellar cores. (3a)–(3c) Three luminosity estimates for these extreme hot cores, derived from the luminosity peak (lower limit), integration of the power-law component of the profile, and total integration of the profile (upper limit). (4)–(6) The eight protostellar cores, located within the extent of the six brightest MF sources of ALMA-IMF, their contribution to the hot core luminosity, and their luminosity computed from Cols. 3b and 5 in Eq. (7). Protostellar cores with a ⋆ tag are tentative. (7a)–(7c) Dust temperature of the protostellar cores, which is estimated from Cols. 3a–3c, Col. 5 and the core size of Table C.8 published at the CDS.
