For each of the ~145 STEREO A or B observations, the following \ninformation is given: event start time, time of the peak pressure, event \nend time, maximum values of pressure, magnetic field magnitude, proton \ndensity and flow speed, and minimum flow speed.  It is expected that this \nlist, given in both PDF and Excel formats, will be updated periodically.",
