Updated "Interactive Reconstruction" Tools in NueAna Display
There currently exists two pages of the NueAna display that were
developed to be interactive reconstruction (IR) tools for hand scanners.
To switch them on, edit the usual RunNueDisplay.C macro such that the
following line is uncommented:
jc->Path("default").Mod("NueDisplayModule").Set("IntReco=1");
The first of the added pages allows the user to interactively select a
sub-sample of the
hit strips in the event.
The second page shows the transverse and
longitudinal pulse height distributions of the strips.
There also exists a feature which carries out a fast simulation of an
EM shower in the detector to show what a "perfect" EM shower would look
like.
The energy of the simulated shower is calculated based on the strips
selected and the vertex and direction of the shower can now be defined
by the user as shown below.
Typical Example:
Some notes:
- The two buttons on the left hand side: "IR: Re-Draw" and "IR:
Calculate" control what is shown on the pages.
- The Re-Draw button will cancel your current selection and
pixel-ize all the strips shown in the second display above i.e. if a PH
cut has been applied, the same low PH strips are also omitted from the
IR selection page.
- The Calculate button uses the selected strips to plot the
transverse and longitundinal distributions.
- The position of the arrows are used as the vertex of that strip
selection, where the z vertex is taken to be the left-most of the two
arrow positions.
- The transverse distributions are NOT around the axis given by the
arrow but rather around the z-axis of the detector
- This is something that can be updated on request
- In the case that the "Do Sim" button on the selection pad is
green, the vertex and angles from the arrows, along with the summed PH
of the selected strips is used to simulate an EM shower and the
transverse and longitudinal profiles of the simulation are overlaid.
- If the "Do Sim" button is red, only the data selection is shown.
- The simulation is relatively slow compared to the rest of the
display - a single simulation may take ~5 seconds
