There are 4 data files.

The files dedt0.dat and dedt90.dat contain the time evolution of the
electron number density at a altitude of 160 km, for solar zenith
angles of 0 and 90 deg.

The files ne-vs-timesza*.dat contain the electron density profiles vs.
altitude for solar zenith angles of 0 and 90 deg., plotted at 500 s
intervales.
