  ExoCross is a Fortran code for generating spectra (emission, absorption) and
thermodynamic properties (partition function, specific heat etc.) from
molecular line lists. Input is taken in several formats, including ExoMol and
HITRAN formats. ExoCross is efficiently parallelized showing also a high degree
of vectorization. It can work with several line profiles such as Doppler,
Lorentzian and Voigt and support several broadening schemes. Voigt profiles are
handled by several methods allowing fast and accurate simulations. Two of these
methods are new. ExoCross is also capable of working with the recently proposed
method of super-lines. It supports calculations of lifetimes, cooling
functions, specific heats and other properties. ExoCross can be used to convert
between different formats, such as HITRAN, ExoMol and Phoenix. It is capable of
simulating non-LTE spectra using a simple two-temperature approach. Different
electronic, vibronic or vibrational bands can be simulated separately using an
efficient filtering scheme based on the quantum numbers.
