On the plot the real time (UT) of the FSP events is shown. Date is shown along the X-axis, the UT - along the Y-axis.

See as an example the real time of the FSP selected for May 1998.

To show in one plot the each of 4 spacecraft's contribution in the FSP situation the following practice is used.
For each spacecraft not only the special colour, but the special line in frame of the each day is used.

for the INTERBALL TAIL PROBE - the first line (and the red colour),
for the INTERBALL AURORAL PROBE - the second line (and the turquoise colour),
for the POLAR - the third line (and the pink colour),
for the GEOTAIL - the fourth line (and the dark blue colour).

The "diamond" symbol shows the times of the either INTERBALL TAIL PROBE or GEOTAIL crossection with the simulative magnetopause.
