During input data import & RAO computation, CASTOR produces human-readable logs that detail each step of the optimisation. More info on logs here.
At the end of the RAO computation, CASTOR produces RAO results detailing the outcome of the optimisation. More info on this here.
These results can be used, along with the input data, in order to produce context-specific output files. You can find examples of such workflows in one of the many GridCapa applications.
