The 'Adjust time-string' dialog


It might occur that your substrings have marginally different zero-point offsets in magnitude/intensity. This can be caused by different instrumentation, or different observational conditions for these substrings.

Zero-point variations entail additional noise in the low frequency domain. To reduce this noise source one has to adjust the zero-point offsets. This can be done through the "Adjust time string" dialog.

Before you open the dialog, however, you should calculate a fit as this routine uses the residuals to calculate the zero points offsets. Select the appropriate attribute to show the set of substring. If weights should be used to calculate the average and the sigma values then select Use weights.

In the list several columns are shown:
In order to adjust the data, select the substrings and press Adjust. The result will be displayed. You may export or print the content of the textbox by pressing the appropriate button.

Please note:
Remember to select "Adjusted data" for all further calculations!
