OAFunc Block

Defines a function that depends on one variable only, which can be of two kinds: interpolatedFromFile or expression. For example, OAFunc are used in MonteCarlo Interactions to define interactions cross sections.

OAFunc Kinds

• interpolatedFromFile

• expression (OAFunc)

• See the “LXCatFile OAFunc” section in the Reference manual.

Example OAFunc Block

<OAFunc mysp>
  kind = interpolatedFromFile
  filename = h2StoppingPower.dat
  # set bounds of the function from min and max x values in the file.
  # option specific to kind = interpolatedFromFile
  # setMinMaxFromFile = 1
  # f has to be >0.
  fmin = 0.
</OAFunc>
