The raw data files are binary files consisting of 20-second dumps. The size of a raw data file for each 24-hour UT-day is about 73 megabytes. The raw data files are not compressed.
Analyzed data files are in the HDF format, which can be read by Tela and other programs. Analyzed files contain the echo intensity and the mean Doppler velocity (zeroth and first moments of the autocorrelation function, respectively) as 3D arrays. The dimensions are the temporal index, the beam number (1..8) and the range index (1..50).
The cleanest way to use these data files is to follow the instructions for using stare.t. Another way is to install Tela and simply load the HDF files directly to Tela. If one wants to use Matlab, one can use export_matlab from Tela. If one wants to use IDL, one can read the HDF file directly (Paul Eglities has done this).
