#Script sh d'extraction de fichier SCA des sequances Diodes a Bruit (DAB) 
#et Data des cycles DRIFT SCAN
#Bash script that extract from SCA files the DAB/DATA phases in DRIFT SCAN cycles
#It is supposed that the sequence is: DAB DATA
#Output SCAXYZ.sum file as
#cycle number,DAB START, DAB STOP, DATA START, DATA STOP
