Notes. Wide-band stands for baseline re-projection of each frequency channel to avoid bandwidth smearing; # comp. is the largest allowed number of simultaneous components in the fit; spectral index stands for the possibility of fitting spectral indices to the components; mosaic stands for the posibility of dealing with observations of a given source with different phase centres (i.e., pointings); and generic vars. stands for the possibility of using generic functions to tie the variables among the different components.
