     the label for heat content 

For example, file 'h22-w0-700m1-3.dat' contains the time series of ocean 3-month (Jan-Mar) 
heat content of the 0-700 m layer for the World Ocean

1st column - year+0.5 (for the yearly heat content) or mid-point
of five-year compositing period (for the pentadal heat content);
2nd column - time series of heat content of OB;
3rd column - time series of the standard error of heat content of OB;
4th column - time series of heat content of NHPB;
5th column - time series of the standard error of heat content of NHPB;
6th column - time series of heat content of SHPB;
7th column - time series of the standard error of heat content of SHPB.

The first line of file contains the labels for each of 7 columns.
