Pre-burst SEDs for the following sources: black symbols – total FIR/(sub)mm emission of G358, green – MM3, blue – MM1, derived from the total FIR/(sub)mm emission by removing contributions from all other sources (including MM3). For MM1 and MM3, the observed values are shown together with the ten best RT fits. At wavelengths beyond 40 μm MM1 dominates the total flux density. The seemingly gap at 10 μm in the MM1 SED is due to strong silicate absorption.
