WinPLOTR demo.1: find and refine a unit cell

• A unit cell search needs accurated reflexions positions. These peaks positions can be determined by an automatic peak search procedure ('Points selection / Automatic peak search' menu option).

  

  The peak position list can be modified by the 'Points selection / Add peaks' (a click with the left mouse button will add the selected X position in the reflexions list) menu option or the 'Points selection / Remove peaks' menu options (a click with the left mouse button will remove the nearest reflexions from the reflexions list) A zoom in the 14-15 deg. 2theta range will show that the 2theta = 14.71 deg. reflexion (found by the automatic peak search procedure) is not really a Bragg reflexion. This reflexion can then be removed from the reflexion list before saving these reflexions positions.
