The law does not require information on other crops. Therefore, the desired values can be identified without much difficulty. There are three different types of data manipulating techniques they are. Limitations of the Current Tabulation There are many regimes of Z and E where most recent tabulations are in agreement at the 5% level, particularly well away from edges in the 5-40 keV range, in lower Z elements, and in f″ or µ PE tabulations.
