SED-fitting results for B1-E. Top panels shows the temperature a) and H₂ column density b) maps across B1-E as measured from SED-fitting to 160–500 μm data, according to Eqs. (1) and (2) and assuming β = 2. Bottom panels show the histograms of the above maps. The temperature histogram c) uses a bin size of 0.3 K and the H₂ column density histogram d) uses a bin size of 1 × 10²¹ cm^-2. For comparison, the dashed line in panel d) indicates the observed column density threshold (from extinction) for core formation from Kirk et al. (2006).
