* these are the meteors I didn't plot, either because there were
too many at a time or because they were too far from my fov;
they might as well be shower meteors

enumeration starts in the 20/02/2003 session
all coordinates in mm from the lower left corner of the map
* too far from my fov to plot properly
velocity scale:
1 - very slow; 2 - slow; 3 - medium; 4 - fast; 5 - very fast
Comments: Conditions were not so nice and I was a bit tired,
so I stopped early. Perseids rates have reached equality
with the rate of all other meteors together.
Please note: d = degrees
