Examples for files, defining analyers and pseudoanalyzers with analog data You may store the data given below in a dataset on your computer. Analyzers are stored in DUMP files with the extension *.DMP, pseudoanalzers are stored in GRAF files with the extension .GRF. Analyzers in DUMP files are read by the command AFETCH, pseudoanalyzers in GRF files are read by the command GREAD.
1. DUMP file of an analyzer with analog dataAnalyzer with a Gaussian distribution X: x values Y: height A: (X = -5 to 5 by 0.01) (Y = exp( - X**2 / 2 ) ),HT0 C: In this example, the x values are implicitely given by a loop, C: and the y values are given as an arithmetic expression 2.

C: In this example, the X and the Y values are explicitely given
C: The X values denote the lower limit of the corresponding bin.
C: The upper limit of each bin is given by the next X value, denoting
C: the lower limit of the next bin.
C: The irregular x channels may result from the correction of
C: ADC data of a measured energy spectrum for detector response. |
