Implementation of the algorithm to find the experimental Bragg curves from the AtTracks. #257

RealAurio · 2025-08-04T19:38:32Z

Added container in AtTrack in order to store the experimental values of (range, eLoss).

Added a base class for possible classes that modify a given AtPatternEvent.

Added the task to apply AtPatternModifications to the AtPatternEvents.

Added the option to pass AtEvent and AtRawEvent to the AtPatternModification.

Added a virtual method to the base class AtPattern that computes the distance between 2 points along the pattern. Implemented it for the case of AtPatternLine.

Implemented a virtual method in base class AtPattern to obtain the parameter at a given point of the AtPattern.

Modified the AtPSAHitPerTB.

Implemented an AtPatternModification which extracts the pair of values for the Bragg curve reconstruction and saves them in the AtTracks.

Added quick test macros to check if this feature works so far.

Generated the Bragg curve histogram and saved it in a new BraggCurve struct in AtTrack.

Added an AtTab to visualize the Bragg curves of the AtTacks.

Implemented the smoothing of the Bragg curves.

Implemented it for the case of AtPatternLine. Implemented a virtual method in base class AtPattern to obtain the parameter at a given point of the AtPattern. Modified the AtPSAHitPerTB. Forgot to change version number. Implemented an AtPatternModification which extracts the pair of values for the Bragg curve reconstruction and saves them in the AtTracks. The AtPatternModifications need to be able to write to disk. Added quick test macros to check if this feature works so far. Generated the Bragg curve histogram and saved it in a new BraggCurve struct in AtTrack. Added an AtTab to visualize the Bragg curves of the AtTacks. Implemented the smoothing of the Bragg curves.

I think this looks good with a few tiny comments. The big one is I don't remember the discussion on moving the brag-curve specific parts to their own derived class.

Should either check for null pointers or we should pass AtPatternEvent as a reference rather than a pointer

+
+   // Iterate over the original tracks and store the modified ones.
+   for (auto track : tracks)
+      modifiedTracks.push_back(GetModifiedTrack(&track, rawEvent, event));


Since we just have references anyway, GetModifiedTrack should probably take a reference rather than a pointer.

This use makes me think it should be a constant reference as well (we are returning a new track)

Yeah, initially I just modified the AtTrack, but since we now want to keep the original AtPatternEvent, I can't just modify them.

Also, by returning a different AtTrack, this would allow this function to get a normal AtTrack and return a derived one, in the future when we implement derived AtTracks. But as mentioned earlier, this gave me problems, so for now I'll just work with normal AtTracks.

I will make it so that the input is a const reference to the original AtTrack.

Should have a doxygen comment explaining this copies event to new branch and modifies each track.

Should have default values for input and output branch name, or those should required parts of the constructor. The class doesn't make sense as an object without them set. Best practices has an object functional an initialization, then use function calls to modify behavior

I have already commented on this, but forgot to press publish review.

I see in a lot of tasks, the default values are given in the constructor of the task, so that's why I put those there. In any case, I will also put the defaults here too even if it's redundant.

Yeah, maybe makes sense. AtPatternEvent should still work with these I guess.

AtPatternModification and AtBraggCurveFinder can be - !, but AtPatternModificationTask needs to be +, or else it does not compile. Also, other tasks are saved as + here.
