+// **********************************************************************************
+// this macro is used to produce an alpha plot/plots for a chosen position in the sky map.
+// In case of several subsamples, the overall alpha plot is also produced.
+// The derotation is possible if Zd and Az are available for each event.
+// Using of OFF data to estimate Nex and Significance is optional (if such data available)
+//
+// input: hillas parameter file/files
+//      optional: a) ascii file with the estimated position of the source
+//                b) ascii file with fit parameters from the OFF sample 
+//                                  (needed for estimation of the background from OFF dada)
+// output: alpha plot for each subsample, overall alpha plot
