Keep "true MC" info also for non-triggered events and telescopes

[moralejo]

I think that this:

ctapipe/ctapipe/io/simteleventsource.py

Lines 732 to 735 in 8f6d5aa

	if trigger.event_type == EventType.SUBARRAY:
	shower = self._fill_simulated_event_information(array_event)
	else:
	shower = None

prevents that the event-wise MC information is filled for non-triggered events. That information is certainly useful for some tests (e.g. checking the fulfillment of some requirements).

Analogously, in triggered events, it seems that the true MC info, like the total number of p.e. from C-photons on the camera, or the pixel-wise number of p.e. from C-photons, is missing as well.

I am closing this, it is a known issue and discussed elsewhere (I mean the reading of all MC events can be done using pyeventio directly, no need to change it here):
