      Review of minutes from the last meeting

We looked over the minutes from the meeting on January 11 
Sean reported that he found and fixed the issue with the 4 ns time 
offset in CPP simulated data.

      Pull Requests on GitHub

Sean described Pull Request #202 
<https://github.com/JeffersonLab/HDGeant4/pull/202>, "Fix for TAGH hits 
for the SRC/CT experiment." Tagger counters, at photon energies lower 
than those in the microscope region are missing. This is due their 
accepted energy range being set to zero, causing unfortunate 
side-effects. This situation was introduced in the solution to Issue 
#182 <https://github.com/JeffersonLab/HDGeant4/issues/182>, "Incorrect 
TAGH counter number assignment." Richard will review the changes 
proposed in the pull request.

      New Frontiers

We discussed other areas of the simulation that need study/development. 
Among them:

  * Kaons in the forward direction
  * Slow kaons in the BCAL
  * Cerenkov photons in the light guides of the FCAL
  * Neutrons and K_L s
