  1. ESA STATUS J. McFadden UC Berkeley SSL

  2. ESA Instrument Papers Both ESA instrument paper are “in press” If you are using ESA data, review these papers for all the caveats regarding ESA data. THEMIS ESA first science results and performance issues, McFadden, J.P., Carlson, C.W., Larson, D., Bonnell, J., Mozer, F., Angelopoulos, V., Glassmeier, K.-H., Auster, U. Space Sci. Rev., 2008. The THEMIS ESA plasma instrument and in-flight calibration McFadden, J.P., Carlson, C.W., Larson, D., Angelopoulos, V., Ludlam, M., Abiad, R., Elliott, B., Turin, P., Marckwordt, M. Space Sci. Rev., 2008
