Creating artificial data



It is easy to generate an equally-spaced artificial data set using Period04. First, make sure that there is a set of active frequencies - or at least one active frequency - in the frequency list of the Fit Module. The current fit will be used for the calculation of magnitude/intensity of the artificial data.

1. Select "Create artificial data" in the Special menu


The "Create artificial data" dialog will appear.

2. Setting the time range(s)


There are two options to define the start and end times of the time series that will be generated: The latter option has the advantage that artificial data for an arbitrary number of different start and end times can be created right away. Please make sure that the file obeys the following format conditions:

3. Calculation settings


Now you have to define the step size. By default a value of 1/(20*Fmax) is given, which provides a good sampling even for the highest frequency. The input field Leading/trailing time gives you the possibility to extend the time ranges by a certain value.

4. Start calculation and output of data


Click on the button "Write data to the following file ..." and choose a file in which the data should be written. If the file already exists you will be prompted whether you want to append the data to the file, replace the file or to cancel the task.
