Exports (writes) data to a file consisting of columns of numbers, separated by blanks. These columns are a date, and results from the curve fits to the data.
When the 'Dates at Equally spaced intervals' toggle button is selected, the 3 text entry boxes for the starting date are active. The default is the date of the first data point. You can specify a different starting date for exported data by entering new values for the year, month and day. All data points are set to the middle of the day. The intervals are determined by the sampling interval.
The user can specify whether the dates should be in decimal year format or in a calendar format.
The user also specifies the output file name.
