Plate.RemoveHotPixels() Method
Replaces every pixel brighter by Threshold than its brightest neighbor with the median of its surrounding pixels. Invalidates ImageStars.
Syntax
Plate.RemoveHotPixels(Threshold)
The method syntax has these parts:
| Part |
Description |
| Threshold (Double) |
The threshold value used to detect a hot pixel (default 0.1) |
| Return (Nothing) |
Does not return a value. |
Remarks
This can really help star detection with both the aperture photometer and PSF centroider/detector algorithm. The default threshold value of 10% (0.1) is OK for most applications.
WARNING This invalidates any ImageStars collections since the detected stars will change as a result of the image modification.
