Demagnetization Analysis in Excel (DAIE). An open source workbook in Excel for viewing and analyzing demagnetization data from paleomagnetic discrete samples and u-channels

The Demagnetization Analysis in Excel (DAIE) program is a single Microsoft Excel file designed for viewing and analyzing stepwise demagnetization data of both discrete and u-channel samples in paleomagnetic studies. DAIE is an Excel workbook and has an open modular structure organized in 10 worksheets.
It is designed for easy use and interactive operation; all the commands and choices can be entered using drop-down menus associated to single cells.
The standard demagnetization diagrams and various parameters of common use are shown on the same worksheet including selectable parameters and user's choices. The characteristic remanence components may be computed by principal component analysis (PCA) on a selected interval of demagnetization steps. Saving of the PCA data can be done both sample by sample, and automatically by applying the selected choices to all the samples included in the file. The whole workbook is free both for use and editing and it is available for download on a dedicated website.
