Plate.ConvolveGaussian() Method

Performs a Gaussian smoothing operation on the image.

Syntax

Plate.ConvolveGaussian(FWHM)

The method syntax has these parts:

Part Description
FWHM (Double) The full-width, half-max (arcseconds) of the Gaussian function used for the convolution kernel
Return (Boolean) Success or failure (generates trappable error on failure)

Remarks

If you use this to improve the S/N before plate solving, and do not wish to have the filtered image written back out to the file, set the Plate.ImageModified property to False after filtering.

Application of this operation to the image will invalidate any plate solution and WCS info that was generated based on the unmodified image. If the original image had WCS, and you wish to write the smoothed image back to the plate file, you should re-solve the plate after this operation and before writing the plate back out.

The FWHM argument is converted to pixel units using the X-dimension plate scale (Plate.ArcsecPerPixelH).
