Since the maximum science return will come from combining data at multiple wavelengths and viewpoints we encourage you to include studies that make use of datasets from the other instruments on-board STEREO, as well as from other missions and ground-based observatories. This will also help us to identify potential planning requirements for the mission as a whole.
