The incoherent scatter transmitter station at St. Santin, France (44.6N, 2.2E) operated between 1963 and 1987. The CEDAR Data Base holds all the data taken from 1966 until the end. Up until June 1973 and after July of 1986, the only receiver station operating was located at Nancay (47.4N, 2.2E). Between 1973 and 1986, 2 other receivers also operated at Montpazier (44.7N, 0.8E) and at Mende (44.5N, 3.45E).

In general, the daytime height range is 105 to 350 km, while the nighttime height range is 200 to 500 km. Before January 1, 1969, the faraday correction is not taken into account in the computation. The spectrum are analysed following the scheme described in Waldteufel (1970). The ion drift component is quasi parallel to the magnetic field as measured by the Nancay receiving station. Because the transmitter is not located at the receiving location, the bisector velocity is plotted for the period when only Nancay data were received. When all 3 receivers were on, then the data are 30 minute averages and the ion drifts in the geomagnetic coordinate system are calculated.

There are 4 areas in the summary plots. There are image plots as a function of height and time of the electron density, electron temperature, and ion temperature. Bin sizes are 40 minutes in time and 40 km in height. For the Nancay period alone there is also an image plot of the bisector velocity, while this is replaced by line plots of the ion drift in the perpendicular east, north and parallel directions at the altitude closest to 300 km. when there are 3 receivers. There are 2 days per page.
