data file are now in ACSII file. The data format is like this.

1.

RUN summary file
This file will be made, when new sub run starts.

 

Table 4: Run header file

#	discription	type	comment
000	Length	int	total length of this file
001	RUN #	int
002	Start event number	int
003	End event number	int
004	# of events	int
005	Start time(sec)	int
006	Start time(micro sec)	int
007	End time(sec)	int
008	End time(micro sec)	int
009	Trig. type/Detector status	int	bit pattern.
010	Trig. type/Detector status	int	bit pattern.
011	Trig. type/Detector status	int	bit pattern.
012	Trig. type/Detector status	int	bit pattern.
013	Trig. type/Detector status	int	bit pattern.
014	Trig. type/Detector status	int	bit pattern.
015	Delimiter	int	(-length)

At this component, The time is cpu time.

2.

event data
This is event by event data-format of each monitor.
last bit of Spill number is pedestal flag. If data is pedestal data, that bit is on.

 

Table 5: spill number

#	event Spill	0-14 bit
#	pedestal flag	15 bit	(if pedestal, bit on)

 

Table 6: event data format

#	discription	type	comment

001	Data ID	int	(station No # Monitor ID # Monitor No)
002	MONITOR DATA ID	int
003	Run #	int
004	Spill #	int
005	Event #	int
006	Triger type	int	(pedestal:1 or data:0 )
007	monitor Condition	int	(ON:1 or OFF:0)
