public class Segment
extends Geometry

An class to represent a CCD Segment. Each Segment is defined by its geometry constants, the parameters for reading it out (prescan and overscans) and the order in which it is read out. A Segment also has a channel number which is used to write the extended headers in fits files. These quantities are as specified in LCA-13501

addGeometryToGrid

protected void addGeometryToGrid(Geometry child,
                                 int p,
                                 int s)

Description copied from class: Geometry

This method must be implemented by all classes extending Geometry. It should internally convert the (p,s) coordinate for the child to its (x,y) position within this geometry.

Specified by:

addGeometryToGrid in class Geometry

Parameters:

child - The child to be added.

p - The parallel position

s - The serial position.
