API field

Custom backtracking width

Explicit width for the custom backtracking option

Unit m

What it is

The collector width the tracker controller uses in its backtracking calculation, in metres, used when the backtracking width option is Custom. Values above the row pitch are reduced to the pitch.

Typical values and how to get it

From the tracker controller settings; close to the collector band width. Choosing Custom on the Model tab with no width entered proposes 1.05 times the collector width. If not given: not used unless the backtracking width is Custom. Choosing Custom on the Model tab fills it with 1.05 times the collector width; a request that selects Custom without a width is refused.
