Popis: | The maximum entropy (ME) analysis of μSR time spectra is used to produce the local field distribution P(b). The ME technique has user-defined constants in addition to the usual data manipulation parameters (such as the time range and binning) used in traditional fitting or Fourier transforms. The ME constants are the default level (used to suppress signals below the noise level) and a looseness factor (used to smooth the line shape). In this paper, we discuss how to automatically select values for these constants to ensure that the resulting P(b) is minimally distorted from the ideal and that the calculated errors are sensible. |
