 +Pairs of tiles (**PoT**) are a cornerstone of the concept of stitching. Here is a collection of information that a **PoT** can be assigned: 
 + 
 +   * Is a displacement known (multiple combinations of these are possible):​ 
 +     * Is a displacement known from stage coordinates?​ This will not have a correlation coefficient assigned. 
 +     * Is a displacement known from manual pre-alignment?​ This will not have a correlation coefficient assigned. 
 +     * Is a displacement known from phase-only correlation?​ This will have a correlation coefficient assigned that has no absolute meaning, and is useful only in relation to other correlation coefficients of the same pair. 
 +     * Is a displacement known from normalized cross-correlation?​ This will have a quantitative correlation coefficient assigned. 
 +   * Are both tiles currently in RAM available?​ 
 + 
 +Multiple combinations of known displacements are possible. For some displacement types, a list can emerge: i.e. several positions can have been cross-correlated with different correlation coefficients.
