El procesamiento de los datos contenidos en los archivos de salida es realizado por un segundo programa, escrito en C que realiza las siguientes tareas:
- Captura desde el archivo de datos especificado por linea de comandos (opcion -f) las trazas del osciloscopio en una matriz de 4x500xn (n=número de eventos registrados) y los timestamps en un vector de n elementos.
- Calcula para cada evento el tiempo desde el evento anterior.
- Calcula para cada traza la linea de base (promedio de las 50 primeras muestras) y se la resta a cada muestra de la traza.
- Encuentra el máximo de cada traza.
- Calcula el área bajo cada traza (ver normalización).
- Realiza una salida en múltiples columnas a la standard output.
Usage:
$analisis [-f FILE] [-t THRESHOLD] [-p PERIOD]
-f FILE set intput file
-t THRESHOLD set threshold level (0 to 128)
-p PERIOD set stats period in seconds
Example:veiga@beba:~/SCOPE$ ./analisis -f 2008-11-07-10001.dat -t 20 -p 10000
# 1226056272
# File starts at Fri Nov 7 08:11:12 2008
# It contains 216 events
# Baseline compensation is performed by trace (first: -2 -2 -1 0)
# The following events present at least one strip above a threshold of 20:
