Abstract:
The eXtended CASA Line Analysis Software Suite (XCLASS) is a toolbox
for the Common Astronomy Software Applications package (CASA)
containing new functions for modeling interferometric and single dish
data. 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.
