| Abstract: |
We present the updated version of FitSKIRT, a method to fit radiative transfer models to UV/optical/NIR images of dusty galaxies. Among various improvements made to the code, the most substantial one is the ability to simultaneously fit to several images. This oligochromatic fitting technique (“oligo” stems from Ancient Greek meaning “a few”) can use several reference images, ranging from the UV to NIR, to constrain the parameters of the model more appropriately. Since the alterations made to the code are quite substantial, we revisit the test case used to test the previous version. This new test case is created to check to which degree the improved FitSKIRT is capable of retrieving the initial parameters. Both the images and parameter values are compared to provide insights and valorize the updated fitting procedure. The result is a highly automated fitting routine capable of providing more accurate constraints on both the distribution and properties of stars and dust in dusty galaxies. |
