This bespoke editor allows examining and modifying the data stored in the file.
The editor's window is split into three parts:
- the top side features a file information panel is located at the top
- the left hand side shows the data in a table view (one column represent a given profile)
- the right hand side displays the selected profile as a curve. There is a level range selector to the right of the curve plot. By dragging or resizing the orange rectangle the actual level range can be set arbitrarily.
