25// //
26// This macro calculates photon fluxes as a function of //
27// - energy and time //
28// - energy and Theta //
29// //
30// It is assumed that the data have been taken in the wobble mode. //
31// This means that there is only one set of data, from which both //
32// 'on' and 'off' data are constructed. //
33// //
34// Necessary input from MC : //
35// - migration matrix (E_est, E_true) as a functioin of Theta //
36// - effective collection areas as a function of energy and Theta //
37// //
38// //
39// The input from MC has to refer to the wobble mode too. //
40// //
41// The macro includes : //
42// - the calculation of Hillas parameters //
43// - the calculation of the effective on time //
44// - the unfolding of the distributions in the estimated energy E_est //
45// //
46// For testing purposes (as long as no real data, no energy estimator, //
47// no migration matrices and no effective collection areas are available) //
48// - event times are generated (according to a Poissonian with dead time)//
49// - a dummy energy estimator is provided //
50// - migration matrices are generated //
51// - dummy effective collection areas are used //
