Plate.ArcsecPerPixelVert Property

 Plate.ArcsecPerPixelVert  (read-write, Double)
 
The vertical angular scale of the image (arc-seconds per pixel, Double, FITS WCS value)

Syntax

Plate.ArcsecPerPixelVert [= Double]

The property syntax has these parts:

Part Description
Value (Double) The vertical angular scale of the image (arc-seconds per pixel, Double, FITS WCS value)

Remarks

This property must be set prior to calling Plate.FindImageStars() or Plate.FindCatalogStars, or Plate.Solve(). It must be set to a value between 75% and 125% of the actual plate scale of the image being solved. After solving, this property will contain the actual plate scale of the image.

This is part of the World Coordinate System requirements.

Changing this value causes recalculation of the [advanced] property MaxMatchResidual as well as the pixel sizes of the (advanced) inner and outer star detection apertures (InnerAperture, OuterAperture).

Legal values range from 0.1 to 600.
