The header of the CDIP timeseries file contains three sections.
The first gives basic information about the sensor: the position,
the sample rate, the sensor type, etc.
The second section contains information about the sensor calibration
factors used to convert the "raw" data to timeseries values.
The third section contains the start time, end time, and sample
length of the data.
Note that only the start time is set in the field and
returned with the data; all other entries in this section are calculated
and added by CDIP's processing programs.
Comments can be added as desired at the bottom of the second section. A dashed
line (----------) separates the header from the data; all comments must be
placed above this line.
Each line of data in the timeseries file contains up to 8 values. The data
values are to be read left to right starting at the top. The first value
corresponds to the start time and the last value corresponds to the
end time.
Note: these data have not passed any CDIP quality control procedures.
