The methods were developed for gamma rays with energies ranging from a few hundred GeV to $\\sim 10$ TeV. An estimator of \\Xmax is obtained, event-by-event, from its correlation with the distribution of the arrival time of the particles at the ground, or the signal at the ground for lower energies.
