+//  1.a  galice -b -q grun.C and produce hits

+// 3. load this macro and run testmerge()
+
+// 4. run test function bellow to compare merged digits with original one
+// 5. to be  noticed output ftom testx() function - should be bigger than
+//    noise because in proces of digitisation we use different seed
+//    of random numbers for diffusion and gas gain
+//    -anyway in place where we have the signal should occur the signal in both casses
+//    - only the amplitude should be different - by factor of sqrt
