Peak coincidence rate, g2 decay time, Efficiency by varying optical density. OD changed by changing repump beam power (by changing the repump laser AOM rf power).

Script files:
-------------
get_od.sh : To obtain transmission data of weak probe beam with and without MOT to get OD (in lepton: programs/fwm_programs/OD_switching)

generate_table.sh : Bash file to generate plotable table from timestamp raw data files.
Output file column format below.

OD_data_fit/generate_table.sh : Get OD for different repump rf powers from the transmission data obtained using get_od.sh 

Parameters:
-----------
776 pump power = 15 mW
780 pump power = 300 uW
Detunings:
   780 : 60 Mhz red detuned from F'=3
   776 : 12 Mhz blue detuned from D3/2, F''=3 for two photon transition
