In the IPTA point lists contain the coordinates (range and azimuth pixel number relative to the reference SLC geometry) of the selected points. Data at these points (SLC values, interferogram values, ...) are stored in point data stacks with each record corresponding to a different SLC or interferogram. The point data stack of mask values contains for each point a flag (0 or 1) which indicates if the data of a point are considered (1) or not considered (0).
The format of an IPTA point list corresponds to a point data stack (with a single record only) of pairs of integers. For each point the record contains the integer valued range and azimuth coordinates relative to the reference SLC geometry of the point list.
The size of a plist is (number of points in the list)*8 bytes.
