Image of the dust temperatures in NGC 2403 produced after the analysis in Section 2.2. The image size and orientation are the same as the size and orientation of the images in Fig. 1. The green circle in the upper left corner shows the 38 arcsec FWHM of the PSF, which is equivalent to the PSF of the 160 μm data. The uncertainties are ≲1 K. The black square indicates the location of VS 44. Regions with temperatures of <20 K at α= 7:37:20 δ=+65:40:00 and α= 7:36:35 δ=+65:32:00 may have been strongly affected by latent image effects.
