Notes

After each commit remember to

• push to origin
• issue pull request
• revert local master
• pull remote changes

Useful commands

• find difference with 2 versions previous
  • git diff HEAD~2
• If you've made 10 local commits, push changes to origin, return to 10 versions previous and pull most recent changes
  • EITHER git push origin master:dalton_new_branch_name
    • OR git branch new_local_branch_name
  • git reset --hard HEAD~10
  • git pull
• deleta a brach from github
  • git push origin master:dalton_new_branch_name

sim-recon Plugins

DAQTree

DAQTree plugin

IntegralWidthvsNumSamps

• Intended to work with mode 8 LED data (waveforms).
• For each channel, will integrate the signal varying the start and stop sample relative to the threshold crossing.
  • Find the relative width for each configuration of integral and find the minimum width.
  • Do this for case with and without pedestal subtraction.
  • log 3345807
• Also used for comparing signals end-to-end to investigate LED width

F250_mode8_pedestal

BCAL_attenlength_gainratio

Plugin to determine the attenuation length and gain ratio for the BCAL channels

• For each channel will
  • Fill a histogram of log integral ration versus position
  • Fit a line to the histogram
  • Extract the attenuation length and gain ratio from fit
• Log entries
  • https://logbooks.jlab.org/entry/3316347

bcal_calib_cosmic_cdc

Plugin to do BCAL energy calibration using cosmic rays.

Analysis

Epics

• Graphical Viewer MyaViewer
• Text access
  • myget : sequenc of channel events for 1 channel
  • myData : All changes in channel values (like myget)
  • mySampler : Interpolated values at regular intervals
  • myStats : Statistics for a particular channel
    • myStats -P -b'2015-12-06 00:15' -e^5m -lvmebcal1:sens1Temp,vmebcal1:sens3Temp,vmebcal1:sens5Temp,vmebcal1:sens6Temp,vmebcal1:sens6Temp,vmebcal1:sens8Temp

BCAL Attenuation Length and Gain Ratios

• Analyze data with plugin BCAL_attenlength_gainratio
