If the parameters 1010 to 1012 are set properly for the delay-line in use the spectra with PosX and PosY as coordinates show
position values in mm. Specific conditions remove incompletely registered events and produce “clean” images. The condition
clean_hit may be replaced by a more refined condition (i.e. on the time sums).
