This feature allows you to combine several 3D Surfaces having different spectral or time ranges. Surfaces are normalized by overlap range. Complete following steps before combining:
- Adjust time zero for each surface. See Time Zero Correction. The time zero for all surfaces has to be the same.
- Make sure that time units setting for each surface is correct. See Time units section.
- If different time-resolution data are used (for example data obtained with Helios and with Eos) choose the appropriate time range for every surface. The time ranges of the data determine the overlap range.(For example, if the first surface has the time range of 0 – 3 ns and the second one has the time range 2 ns – 10 ns then the overlap range is 2 ns – 3 ns).The overlap range should be chosen so that there are no individual features (spikes, etc.). For example, a spike in the beginning of the Helios data can be perturbed by the Eos data (if the overlap range is 0 – 3 ns).
- Save all data before combining.
- Select menu item Surface ->Combine multiple surfaces and choose the files saved on step 4.
This example below is the result of combining date obtained by Helios and Eos instruments. The prepared Eos data are shown on Figure 40. The time zero was corrected and time range is set to 2 - 2000 ns. The range 0 - 2 ns was cut out as it can disturb the Helios data. The early part of the Helios data contains some spikes (see Figure 41) so the Eos range was chosen to not cover the beginning of the Helios data.
The result of this procedure is shown on Figure 41.
