Every data set in Vx0 system that is described by a SPASE Numerical Data Resource XML file contains information about who should be acknowledged for the use of the data in any publication. For example, the Cluster II FGM data carry the tags:
<Acknowledgement>NASA; Andre Balogh; Elizabeth E. Lucek</Acknowledgement>
Publications should include the acknowledgements for each data set obtained through the VMO. In addition, the VMO requests that our effort be acknowledged as well by including acknowledgement that the data used in the publication were obtained from the NASA Virtual Magnetospheric Observatory.
