Design Goals

• flexible and expandable modeling algorithm implementation

• provide various parameter optimization choices and robust error estimations

• the comparison can be made in either image and visibility domain

• handle multiple images/cubes simultaneously and treat blended line/objects together

• straightforward parameter setting: the emission model was built upon parameters describing “physical” properties of each object; the emission models can be easiliy translated into the data obatined in radio (frequency) or optical (wavelength) with pre-defined system response functions

• provide data/model visulizations (xy/pv-moms) and clear diagnostic plots for parameter fitting goodness (chi^2/posterior-prob)
