Timeline (Baselined),
Revision 13, dated 02/15/03 7:00 a.m. CST, from the Integrated
Timeline Team. - GPS-derived
latitudes and longitudes are plotted on the map at 0.96
second time intervals,
although there are numerous data dropouts. The symbol used
for points from the trajectory
data file is a red dot. - The
time tags of events from the Master Timeline sometimes fall
between trajectory data
points, and in some cases they occur during GPS data dropouts.
In these cases, the correct
location of the event is indicated by a blue dot.
