Cloudshine radial profiles across the TMC-1N interstellar filament. The blue, black, and red lines show the profiles measured by Malinen et al. (2013) in the J, H, and K photometric bands of the WFCAM instrument, respectively, smoothed to 40′′ angular resolution. The circles of the same colours show our fit to these data (CMM+AMMI and , see Sect. 4.2 for details about the modelling). Our model is smoothed to the same angular resolution as the data and the synthetic photometry in the WFCAM filters is computed at each position.
