Radial temperature profile for cores 1−4 in ISOSS J22478+6357 and cores 1−6 in ISOSS J23053+5953. The radial H₂CO temperature profile is shown by the black data points. The outer radius r_out, estimatedwith the clumpfind algorithm in the continuum data (Table 4), is indicated by the dash-dotted purple vertical line. A fit to the data and its uncertainties (±1σ) are shown by the red solid and dashed lines, respectively.
