The time string tab


The time string module is dedicated to edit time string data. In the upper part of the time string tab buttons for loading and saving time string data are located:
Import: Import time string data. If the current project is not empty then the old time string data will be replaced and the remaining project data (frequencies, fourier spectra and the log) will be erased.
Append: Append a time string to the current project.
Export: Save time string data to a file.

The text box next to the buttons contains the full path-names of the files from which the data have been imported.
Below the text box some properties of the currently selected time string are shown:
Points selected: The number of points that are currently selected.
Total points: The total number of points in the time string.
Start time: The lowest time value of the currently selected time string.
End time: The highest time of the currently selected time string.
Checkbox "Time string is in magnitudes" If your data are in magnitudes instead of intensity this option should be selected. In case of magnitudes the y-axis of time string plots will be reversed - it is also important for epoch calculation. By default the program assumes that the data are in magnitudes. It is possible to change the default setting by editing the Period04 preferences.

The main part of the 'Time string' folder are the 4 list boxes. Each list box represents an attribute for the time string data. If you didn't read in any attributes then the lists will show the entry "unknown". The names of the attributes can be changed by clicking on the headings on the top of each list. You may also change the default names by editing the preferences file.

In the lower part of the time string module there are several buttons:
Edit substring Click on this button to edit the properties (name, color and weight) of the currently highlighted items (substrings) of the list. See "The Edit substring properties dialog" for further details. This dialog can also be accessed by a right click on a specific substring and selecting "Edit substring properties" in the pop-up menu.
Display table: Display a list containing the full information on all data points of the selected time string.
Display graph: Plot the selected time string and, if the resolution of the viewport is high enough, show the current fit as well.

The columns in the time string module provide a pop-up menu. The following entries are currently available:
Edit substring properties Opens a dialog to edit the properties of a substring.
Combine selected substrings Opens a dialog to edit the properties of a substring.
Select all substrings Selects all substrings in the current list box.
