Triton BathyPro - Manual (Page 107)

The system computes a hyperbola from the paired contact and XTF files. From
this, the system builds a record of numerical latency from the set of generated
hyperbolas. You need at least two CON/XTF pairs to generate a latency number
(in milliseconds). The more CON/XTF pairs you have, the more accurate the
latency output.
To do a latency test using sidescan sonar data (per Figure 53)
1. From BathyPro’s main menu, choose Patch Test → Latency with
SideScan Imagery Data.
The system displays a patch test dialog box which becomes your
workspace for measuring latency of sidescan data (Figure 59).

2. Click Select File.
The system displays the Select contact dialog box, where you can specify
one or more contact files taken from the XTF files that appear in your
DTM project file’s list of XTF files.
3. Specify your contact (CON) file(s) and click OK.
