Hi @jsitarek, thanks for your modifications, in general it looks fine for me, as you already succeeded in processing MAGICSoft MCs with this changes. Still, I have some ideas to make it more automatically as I already commented, and so if you don't mind I would like to push a new commit with my modifications on this script, is it fine for you?

Hi @YoshikiOhtani do you mean a new commit in this branch, or to make a separate PR from the main branch?

[YoshikiOhtani]

Hi @jsitarek, I meant a commit to this branch, but if you prefer I can make a new PR after merging this branch to master.

I think it is best if you commit to this branch (just wanted to make sure that this is what you actually meant).
If you are going to make some clean up, I had to copy a container that you use in another script (and rename it to ...MC), maybe this container can be defined somewhere in the main files of the module (but either way this will be somewhat temporal, because in the end we will need to make the format consistent with ctapipe standard containers)

Hi @YoshikiOhtani
I made two minor changes to this branch, I hope it does not interfere with your changes

I finished cleaning up the code. Let me briefly summarize the changes here:

• It now automatically checks the data type and processes it differently between real and MC data. So one does not need to give "--use-mc" argument.
• It stores the telescope positions obtained from the MAGICEventSource, but the telescope IDs are reset for the convenience of the combined analysis with LST-1 (tel_id = 1).
• Removed the author name because it is expected that more people may contribute on this script in future
• Updated the merge_hdf_file.py so that it can be used for MAGICSoft MC data files

I tested the updated scripts to some of MAGIC data and it worked fine. It would be great if someone could check them and give me some comments.

By the way it accidentally contains a bug fix commit which is not related to this discussion, but I see that the bug has been already fixed by Elli and so please ignore the commit.

Since I would like to make another pull request about dead time calculations based on these changes, let me merge this to the master. I confirmed that the updated script works fine so I hope it doesn't make any problems.
