(10th line)recording start time

This time includes the effect of delay time 15 seconds in the strong-motion recorder so, the true start time is obtained by subtracting 15 seconds from the Record Time.

(13th line)number of sensor channels

The strong-motion seismograph of KiK-net has 6-channel acceleration sensors. Relationship of the channels and data file suffix are described below.

channel	underground/surface	suffix
1	underground	NS1
2	underground	EW1
3	underground	UD1
4	surface	NS2
5	surface	EW2
6	surface	UD2

(15th line)maximum acceleration

This value is subtracted the avarage of whole data from original value.

(over 18th line)strong-motion data

They are signed integer of 7 figures.
