EXPLANATION OF PLOPTEN Dnata
Figures 4.1 through 4.7) show the data from the world-wide
sampling network, plotted in accordance with the key shown on
each map.

Because of the. greater density of reporting stations
in the United States, that data is shown on separate larger scale
maps.
.
In addition to the data from the fixed station, the maps
also include the results of non-routine observations made at
selected locations for a few days following each burst. Such.
_ observations are indicated as "Special Data" on the northern
hemisphere maps. Ordinarily, these observations consist of a
series of shorter period collections rather than the. 2h-hour samples
taken by the routine network. Since the exact times of observation
‘are unavailable, these data are listed in an arbitrary order on
the appropriate day.
All activity has been extrapolated to collection date on the
basis of the MIK= burst miess otherwise indicated. Where it was
clearly evident that debris from the KING burst was present at a
station on a given day, the activity for that day and all succeeding .
- @ays was extrapolated on the basis of the second burst and indicated
by Ryn:
On the United States maps, areas nw
which at least one gummed
paper at a station had activity of 500 d/m or more are delinsated
by a solid line to show the movement of individual patches of debris
across the country.
The data has been closely inspected for inconsistencies.
Questionable data, which would be misleading if accepted as correct,
have been enclosed in parentheses. In scme cases, the data is
doubtful because they require unreasonable (and in some cases
impossible) wind speeds, others are questioned because they are
than two gummed paper samples on one map, but none on the day before
or after, no doubt the result of misdating the data card in the
field. Obviously, a portion of the data is not correctly plotted,
but the inconsistency. is obvious without being so marked. In addition,
