This guide describes how to use the SKIRT code and the Python Toolkit for SKIRT (PTS). The table below lists the various topics. You can review them in the presented order or simply skip to topics of interest. We highly recommend that you work through the hand-on tutorials (marked with a keyboard icon). See the Icon legend at the end of the page, below the table.
