Notes:
- Short, flat,
top section
- Diagonal edge,
from lower left to upper right.
- Edge. Note
that it is not parallel with the edge in note 2. Note that included
angle formed with edge 2 is approximately 45 degrees.
- Layer on top
of lower portion of symbol #15, fully obscuring the lower portion of
the symbol.
Note the narrowness
of the top of the symbol, and specifically the angularity, and absence
of curvature, or loops.
A 0 needs wide curvature
at the top of the symbol. There is support for neither. This excludes
a 0.
A 2 needs wide curvature
at the top of the symbol, and an opening to the upper left of an upper
loop. There is no support for this. This excludes a 2.
A 3 needs wide curvature
at the top of the symbol, and an opening to the upper left of an upper
loop. There is no support for this. This excludes a 3.
An 8 needs a loop
at the top of the symbol. There is no support for this. This excludes
an 8.
A 9 needs a loop
at the top of the symbol. There is no support for this. This excludes
a 9.
The initial candidates
for symbol #15 are 1, 4, 5, 6 and 7.
The width of the
top of the symbol is too narrow to support a 7. Further, the diagonal
of the symbol is connected to the upper left of the symbol and not the
upper right as would be required for a 7. There is insufficient support
for a 7 and it is therefore removed from the symbol candidate list.
The edge located
at note 3 is inconsistent with a 5, further the width of the top of the
symbol is too narrow to support a 5. There is insufficient support for
a 5 and it is therefore removed from the symbol candidate list.
There is inadequate curvature at the top of the symbol to support a 6.
Further, the 45 degree included angle between the edges 2 and 3 conflict
with the features required for a 6. There is insufficient support for
a 6 and it is therefore removed from the symbol candidate list.
The narrow width
of the top of the symbol supports a 1, however the 45 degree included
angle between edges 2 and 3 conflict with the features required for a
1. There is insufficient support for a 1 and it is therefore removed from
the candidate list.
The narrow width
of the top of the symbol supports a 4, and the 45 degree included angle
between edges 2 and 3 are consistent with the features required for a
4.
