The resulting induced charge is summed for all propagated charge carriers and returned as a `PixelCharge` object. The number of neighboring pixels taken into account can be configured using the `induction_matrix` parameter.
The resulting induced charge is summed for all propagated charge carriers and returned as a `PixelCharge` object. The number of neighboring pixels taken into account can be configured using the `distance` parameter.

## Parameters
* `induction_matrix`: Size of the pixel sub-matrix for which the induced charge is calculated, provided as number of pixels in x and y. The numbers have to be odd and default to `3, 3`. Usually, a 3x3 grid (9 pixels) should suffice since the weighting potential at a distance of more than one pixel pitch normally is small enough to be neglected.
* `distance`: Maximum distance of pixels to be considered for current induction, calculated from the pixel the charge carrier under investigation is below. A distance of `1` for example means that the induced current for the closest pixel plus all neighbors is calculated. It should be noted that the time required for simulating a single event depends almost linearly on the number of pixels the induced charge is calculated for. Usually, for Cartesian sensors a 3x3 grid (9 pixels, distance 1) should suffice since the weighting potential at a distance of more than one pixel pitch often is small enough to be neglected while the simulation time is almost tripled for `distance = 2` (5x5 grid, 25 pixels). To just calculate the induced current in the one pixel the charge carrier is below, `distance = 0` can be used. Defaults to `1`.

## Usage
```ini
[InducedTransfer]
induction_matrix = 3 3
distance = 1
```
