Plate.FullWidthHalfMax Property

 Plate.FullWidthHalfMax  (read-only, Double)
 
The full-width-half-max (FWHM) of the stars in the plate, pixels

Syntax

Plate.FullWidthHalfMax

The property syntax has these parts:

Part Description
Value (Double) The full-width-half-max (FWHM) of the stars in the plate, pixels

Remarks

This property is available after calling Plate.FindImageStars(). It is not necessary to first solve the plate. The value is in pixels to avoid the need for first plate solving it (needed to get accurate mesaure in arc seconds).

The FWHM is measured by doing individual Gaussian PSF fits to the 20 brightest unsaturated stars in the plate.
