2. Array Options

There are five different array options: The first is the standard VLBA involving only its 10 dedicated stations. The other four options are known as "VLBA-plus", which involve adding additional antenna(s) to the dedicated VLBA stations: VLBA + single dish VLA (Y1), VLBA + three VLA antennas (Y3), the High Sensitivity Array (HSA), and Global VLBI.
