WebThe .fxye format for GSAS has an intial header line followed by a variable number of comment lines (prefixed by a # character), then an addtional header line. The data are listed next in three columns: 1st column is 2θ position (in centidegrees, i.e. degrees × 100), 2nd is intensity, and 3rd is standard uncertainty for the intensity values (esd).
