 model_ensemble_averaged_parameterized_scattered_image (model_visibility_amplitude &model, double pivot_frequency=230e9)
 
virtual size_t size () const
 Size of the supplied model image, i.e., number of parameters expected.
 
virtual void generate_model (std::vector< double > parameters)
 Takes model parameters and generates.
 
virtual double visibility_amplitude (datum_visibility_amplitude &d, double accuracy)
 A user-supplied function that returns the visibility amplitude in Jy. Takes a datum_visibility_amplitude to provide access to the various accoutrements. While this provides access to the actual data value, the two could be separated if necessary. Also takes an accuracy parameter with the same units as the data, indicating the accuracy with which the model must generate a comparison value.

Detailed Description

Scattering implementation assumes we are in ensemble-averaged (Gaussian blurring) regime. This appends a set of seven scattering model parameters, consisting of:

  • parameters[model.size+0] ... Major/minor axis at pivot frequency.
  • parameters[model.size+1] ... Frequency power law index of major/minor axis.
  • parameters[model.size+2] ... Minor/major axis at pivot frequency.
  • parameters[model.size+3] ... Frequency power law index of minor/major axis.
  • parameters[model.size+4] ... Position angle at pivot frequency.
  • parameters[model.size+5] ... Position angle frequency dependence normalization.
  • parameters[model.size+6] ... Position angle frequency power law index.

void set_mpi_communicator ( MPI_Comm  comm)
virtual

Defines a set of processors provided to the model for parallel computation via an MPI communicator. Only facilates code parallelization if the model computation is parallelized via MPI.

Reimplemented from model_visibility_amplitude.
