% Descripton: |
| 22 |
% This function averages the data. The field to average is defined by |
| 23 |
% 'fln', and the loaded, pre-averaged data is 'data'. The field |
| 24 |
% 'absmonths' is the time axis given in months (1,13,25,... are assumed |
| 25 |
% to be Janurary), and is returned in 'datatime' so that there can be a |
| 26 |
% time axis for every experiment / configuration setting. It is |
| 27 |
% important to remember that this function assumed monthly data! |
