====== Plot Radius Limits ======
The plot radius factor (PRF) for prism with basal area factor 10 is 2.75.
For your own prism (other than BAF-10) calculate PRF and fill in blank 
column below. Use for trees of any size to determine if tree is in or out
of plot. Select from table for desired DBH and sum up to get limit in feet.
MOVE the decimal as needed.

^    ^Point limits in feet ^|
^DBH ^BAF-10 ^BAF---        |
|1   |2.75   |              |
|2   |5.50   |              |
|3   |8.25   |              |

|7   |19.25  |              |
|8   |22.00  |              |
|9   |24.75  |              |
|10  |27.50  |              |


Example: For 12.8" DBH Tree
^      ^DBH   ^Limit ^    |
^      |10.0  |27.5  ^    |
^      |2.0   |5.5   ^    |
^      |.8    |2.2   ^    |
