Pixel coordinate reconstruction uses

• tile ideal geometry,
• tile center positions,
• tile N·90 rotation and tilt angles.

Pixel coordinates in the detector should be accessed by method like

            (x, y, z) = get_pixel_xyz_in_detector(tile_number,row,column),

or look-up tables for consecutive pixel indexes

              (xarr, yarr, zarr) = get_xyz_arrays_in_detector().

Summary

Suggested method for imaging detector geometry description provides simple and unambiguous way of pixel coordinate parametrization. This method utilizes all available information from optical measurement and design of the detector and tiles. All geometry parameters are extracted without fitting technique and presented by natural intuitive way.
