+of astrophysical sources with almost any existing or planned X-ray
+observatory.  The goal of SOXS is to provide a comprehensive set of tools to
+design source models and convolve them with simulated models of X-ray
+instruments.  This package was originally developed to support the
+@url{https://www.lynxobservatory.org/,Lynx X-ray Observatory} mission concept,
+but has evolved to support other missions as well.")
