The center plate
Hello,
In script functions, for example Image.EstimateRaDec what is defined as "the center plate"?

Re: The center plate
Hi Patrick,
"center plate" is a geometrical definition of the coordinates (x/2,y/2) where x and y are the numbers of the pixels of the sensor.

Thank you. Very clear.

Re: The center plate
Hello again,
Further to the response above,Is the central plate the center of the sensor, or perhaps could it be also the center of an image or a rectangle?
What is the function of the Center plate selectors in the Astrometry window?

Re: The center plate
Hello Patrick,
the answer to the first question is yes, it could be also the center of an image. According to my understanding the always a geometrical definition (i.e. an image, either cropped or not, is centered at coordinates x and y).
The center plate selection is not in the Astrometry window but you can always select it with View -> Grid.
I hope to have understood your question.

Thanks for the answer to the first question.
The Center plate details I referred to is seen if i follow the Tutorial on Plate Solving (AA8 SP4 User's Guide p. 16) then select Astrometry from the Tools menu.

Re: The center plate
Hello Patrick,
in the Astrometry panel of the Tool Menu the item "Center Plate", as far as I have understood, indicates the precision in pixel (0.5 is the suggested precision) of the position of the center plate once the Astrometry calculation have been done. It is indicated by a red inclined cross in the image you are analysing.

Alessandro,
Thanks for the response.
This all seems outside my level and is best left alone by me.
