Message:

 Changed default pulse position in the FADC window. Now the high gain peak
 is around the 5th slice (changed default value of trigger_delay from 25 to
 19 ns)

+// Set as default option that of writing all event headers to output file,
+// not only those of the triggered events. To disable it, set the input card
+// flag "no_write_all_event_headers".
+//
+// Changed such that output images for events below the minimum number of
+// photoelectrons nphe2NSB required to simulate the noise (NSB & electronic)
+// will be empty. This will avoid the problem of these events being processed,
+// without any noise, later in the chain. Although those images are not in the
+// output, one can still check in the headers (MMcTrig) how many such events
+// with less than nphe2NSB photoelectrons would have triggered.
