get_sed() and get_image() now return SED and Image objects that contain meta-data in addition to the data itself. For example, images contain information about the field of view (in physical/angular units, where appropriate), and information about the units is also included. The old syntax of wav, nufnu = m.get_sed(...) will still work, but the meta-data will not be accessible in those cases.
New library of dust models, accessible in Library of dust models
It is now possible to read in previous models completely, including the density structure, geometry, sources, dust, and configuration, using the read() method. In addition, new methods individual methods use_sources(), use_image_config(), use_run_config(), and use_output_config() allow more detailed control over reading in parameters from previous models.
It is now possible to force overwrite Hyperion output from the command-line using the -f option:
hyperion -f input output
or when using the individual fortran binaries:
mpirun -n 8 hyperion_car_mpi -f input output
This will likely be useful for users of computer clusters who don’t want a job to fail just because the output file already exists.
Regular Cartesian grids can now also be exported for viewing in yt (as was previously possible for AMR and Octree grids).
A new function, run_with_vertical_hseq(), is available to help with the calculation of vertical Hydrostatic equilibrium in disks. Note that this feature is still experimental and should be used with care.
A new function, tau_to_radius(), is available to compute, for spherical polar grids, the optical depth from infinity to a given radius.
