Fig. 5. The observed (left column), modeled (2nd column) and residual (3rd column) images of M 51 for the GALEX FUV (top row), IRAC 3.6 µm(2nd row), IRAC 8 µm (3rd row), MIPS 24 µm (4th row) and PACS 160 µm (5th row) wavebands. The observed images have been convolved to theresolution of the PACS 160 µm filter, i.e. the resolution of all input parameters maps in the radiative transfer code. The size of the PACS beam (∼12 arcsec) is indicated in the bottom left corner of the model images. The last column shows the histogram of residuals (normalized to 1).

Fig. 5. The observed (left column), modeled (2nd column) and residual (3rd column) images of M 51 for the GALEX FUV (top row), IRAC 3.6 µm(2nd row), IRAC 8 µm (3rd row), MIPS 24 µm (4th row) and PACS 160 µm (5th row) wavebands. The observed images have been convolved to theresolution of the PACS 160 µm filter, i.e. the resolution of all input parameters maps in the radiative transfer code. The size of the PACS beam (∼12 arcsec) is indicated in the bottom left corner of the model images. The last column shows the histogram of residuals (normalized to 1).
