= Action Items =

* Produce documentation for implementation of timing algorithms and constants (Andrei)
* <strike> Andrei to send reference to Will for BCAL_mevPerPE constant </strike> Send a couple of weeks ago
* <strike> Will will extend the range of the plot for simulated resolutions to higher energy (e.g. 5 GeV) </strike> [https://logbooks.jlab.org/files/2016/11/3435635/smearing_update_0.pdf Updated Log Entry]
* <strike> Check that the charged track extrapolation inside the BCAL follows the magnetic field. </strike> The tracking is following tracks through the magnetic field.

# Announcements
#* Accelerator is running smoothly for Hall A at 5 pass. The decision has been made not to reinstall the separator cavities during the run. We have requested to get at least on week of beam before the shutdown.
# Action Items
#* Several items completed.
# Run preparations
#* Long cosmic-ray run completed over Thanksgiving. Beni is planning to take more comics this weekend. 
#* We should check that LED pulsers are on for both Bcal and Fcal.
# FCAL update
## Bases (Jon)
##* Matt stresses that Chris should diligently continue repairing bases
##* Chris is repairing about 5 bases per day.
##* Identified the first verified case of a bases with nominal fixes (by Chris) has failed after about 60 hours of testing
##* Base has rebounded on its own. Waiting for continuous failure to remove from test setup and let Chris diagnose failure.
##* Fernando continues to check design for possible weaknesses.
## [[Media:EfficiencyStudiesDec1.pdf  | Studies using omega decays]] (Jon)  
##* Work in progress
##* Updated software has been used to look at omega->pi+pi-pi0, pi0->g(g), and omega->pi0(g) and compare with previous results
##* Considerable improvement in the use of the kinematic fit for those reactions
##* Mark: Can one also look for bachelor photons? Yes, but completed yet
##* Curtis: What is the beam energy selection? Eg selection is 8.1-9GeV. Could expand to lower energies and increase statistics
##* Mark: What was the confidence level cut? CL cut is 1%. 
# BCAL update
# Calibrations
# Reconstruction and Simulation
##[https://logbooks.jlab.org/entry/3441888 BCAL Clustering charged particles try1] (Will M.)
##* Will has completed a nice study of possible clustering strategies for charged particles. 
##* Initial algorithms did not perform much better than the existing neutral clustering.
##* Plan to investigate clustering based on empirical shower shapes.
##* Feedback is welcome on the posted log entry  
# Any other business
#* George is looking into the pi0->ge+e- decay for calorimetry studies as well as an easy rare decay.
#* With the reduction in the accelerator schedule, we should devote effort to completing NIM articles for the Bcal and Fcal.
