/*****************************************************************

 DISPLAY -- Display calibrated data

 datafile:
    A calibarted root file which came out of callist,
    e.g. 20170727_006_C.root

 lvl1, lvl2:
    Lower (1) and higher (2) cleaning level


 To run the macro from the command line (assuming you are in a directory
 Mars/build where you have built your Mars environment) ou can do

    root ../hawc/display.C\(\"filename_C.root\"\)

 or from within root

    [0] .x ../hawc/display.C("filename_C.root")


 You will get a status display. You can step through the events
 either by selecting Loop/SingleStep from the menu bar or
 by pressing the space key in the status window.

 Note that as a default (see below in the code), events which
 do not survive image cleaning are skipped.
