[1]: Hexadecimal channel number (2-byte)
[2]: Recording flag
[3]: Delay time on a circuit (ms)
[4]: Station code
[5]: Motion component code
[6]: Reduction ratio of monitoring waveform (expressed as the integer exponent of a power of 2)
[7]: Quantization bit rate in A/D conversion
[8]: 传感器的敏感度 (单位是伏特每输出单位,其中输入单位由 [9] 列指定
[9]: 输入单位。使用MKS系统: "m" 代表位移, "m/s" 代表速度, "m/s/s" 代表加速度。
[10]: Natural period of the seismometer (s)
[11]: Damping constant of the sensor
[12]: Amplification factor applied to sensor output prior to A/D conversion (dB)
[13]: Quantization width in A/D conversion (V), a.k.a. LSB value
[14]: Station latitude (degrees). A positive value indicates North latitude.
[15]: Station longitude (degrees). A positive value indicates East longitude.
