Here, I have embedded a proton (P = [0.6,0.0,1.0] GeV) into a Au+Be event at the pixel level.
This was with the slow simulator provided by Gulshan (but now debugged and
with functionality from SUNYSB), and based on a
macro by Dieter.
The hits are tagged according to the geantid of the simulated particle, based on the pixel tagging
algorithm revived by Chris and Paul at SUNYSB.
Using the latest version of the 2dh (H2Dv1.20 released 4 december 1997), based on SUNY-local fixes
by Paul, we can tell which hits are from the embedded track.
Once the simulation/embedding was over, the data was processed by:
- Blue dots are hits unused by the tracker
- Green triangles are hits used by the tracker (jtf)
- Black triangles are hits tagged by h2d as coming from the embedded proton
- Red triangles are hits belonging to the reconstructed track that was
associated (by trk_evaluate) with the embedded proton
