Among the tools is the myXCLASS program which calculates synthetic spectra by solving the radiative transfer equation for an isothermal object in one dimension, whereas the finite source size and dust attenuation are considered as well. Molecular data required by the myXCLASS program are taken from an embedded SQLite3 database containing entries from the Cologne Database for Molecular Spectroscopy (CDMS) and JPL using the Virtual Atomic and Molecular Data Center (VAMDC) portal. Additionally, the toolbox provides an interface for the model optimizer package Modeling and Analysis Generic Interface for eXternal numerical codes (MAGIX), which helps to find the best description of observational data using myXCLASS (or another external model program), that is, finding the parameter set that most closely reproduces the data. Description: The Common Astronomy Software Applications package (CASA) package provides a powerful tool for data post-processing, but contains only rudimentary functions for modeling the data. On the one hand the toolbox offers the possibility to model data using the myXCLASS program, which is a one-dimensional radiative transfer program using CDMS/JPL molecular data. Additionally, the toolbox provides an interface for the MAGIX package. MAGIX provides a framework of an easy interface between existing codes and an iterating engine that attempts to minimize deviations of the model results from available observational data, constraining the values of the model parameters and providing corresponding error estimates. Many models can be plugged into MAGIX to explore their parameter space and find the set of parameter values that best fits observational/experimental data. Furthermore, the toolbox contains an interface for VAMDC (Virtual Atomic and Molecular Data Centre) and the CDMS (Cologne Database for Molecular Spectroscopy) database. File Summary:
