# kCMFormatDescriptionCameraCalibration_RadialAngleLimit

## Declaration

```swift
let kCMFormatDescriptionCameraCalibration_RadialAngleLimit: CFString
```

## Discussion

Discussion Specifies the outer limit of the calibration validity in degrees of angle eccentric from the optical axis. The value is linked to radial distortion corrections with k1 and k2.
