XMatch_Coord help page



  GENERAL DESCRIPTION

  Given two lists of points, referred to reciprocally translated and
  rotated reference frames on a plane (x, y), the XMatch_Coord
  application estimates the relative shift and rotation and applies
  an inverse transformation to the points in list 2, in order to
  map them onto list 1.
  The estimation is performed by means of a Newton-like algorithm.
  A list of reference points, representing a sub-set of list 1, must
  be supplied, along with a guess of the relative shift and rotation
  between the reference frames.
    
 
 
  PARAMETERS

  'x-axis translation':
      Guess of the x-coordinate of the origin of reference frame 2
      with respect to reference frame 1.

  'y-axis translation':
      Guess of the y-coordinate of the origin of reference frame 2
      with respect to reference frame 1.

  'rotation angle':
      Guess of the angle between the x-axis of reference frame 1
      and the x-axis of reference frame 2. It must be expressed in
      degrees, measured counter-clockwise from 1 to 2. 



  CONTROLS/BUTTONS

  'Match':

      and apply an inverse transformation to the points in list 2.
