== List of changes in Run parameter ==
'''Run number range : Event'''
*23211 ...     : accumulation trigger changed from 2-plane to 3-plane
:::            : kept running with 3-plane accum trigger, all planes unmasked
*23003 - 23094 : laser not working, can be used for background runs.
*23247 - 23258 : electron detector found with its threshold power supply at 'output off' [[http://hallcweb.jlab.org/hclog/1201_archive/120121063849.html hclog]]
*23276 - 23280 : electron detector found with its threshold power supply at 'output off' [[http://hallcweb.jlab.org/hclog/1201_archive/120122002842.html hclog]]
*23657 - 23673 : beam current at ~60 uA
*23677 - 23765 : the laser cycle On:Off period was changed from regular 60:30 to 50:25 (rootfiles don't exist)
*23766 - 23773 : beam off, calib input runs
*23774 - 23835 : beam off, (LED linearity tests, DAQ tests etc)
*23836 - 23913 : transverse regular running
*23914 - 23926 : transverse running, I=75, edet trigger Gatewidth scan 
*23933 ...     : regular longitudinal running , I = 180uA
*23939 - 23945 : edet trigger gatewidth scan with changing trigger and mask conditions
*23946 ...     : back to 3-plane trigger, all planes including sick channels of plane-4 unmasked
*24141 ...     : changed slave firmware to 0x321B, master board firmware to 0xAA0D, has data for two PWTLs but 2nd one not working yet
*24175 ...     : masked off plane 2: strip 10 & 41; plane 3: strip 62
*24141 - 24242 : we do not have event-mode and scaler data for this period, the address-mapping in header file wasn't correct
*24242 ...     : we now have data corresponding to two different PWTL
*24296         : this was a regular beam run, but I had my chipscope plugged into the master board, so if this shows a non-standard result, it should be taken with a pinch of salt
*24296 ...     : updated master board firmware to 0xAA0E, in the previous revision, the accum trigger corresponding to PWTL2 was not clocked at the final output stage, hence those patterns where the overlap between multiple triggers was only one clock wide were lost.
*24319 : changed the slave board firmware from 0x3219 to 0x321B. Now pldelay readout works
*24328 ...     : changed the 2 ribbon cables that connected slave-2's PWTL2 output to the master board. Now the length of this cable is same as those used in slave-1 and in PWTL1 trigger.
*24349 - 24365 : PWTL2 scan, somehow, this data is 'affected' Ac/Sc ratio sticks out
*24581 - 24594 : PWTL scan at low current (60 uA)
*24747 ...     : flipper removed from laser, hence finite contribution from laser-"off" too; laser-on:off changed to 90:45 from 60:30
*24761 - 24762 : in 1st run, laser was scanning; 2nd, flipper was in; to study effect of finite laser during "laser off"
*24814 - 24821 : threshold was found off, so edet had no hits; https://hallcweb.jlab.org/hclog/1203_archive/120331072136.html
*25008 - 25251 : (approx run numbers) beam energy was at 0.879 GeV
*25213 - 25248 : beam off
*25285 - 25300 : Moller Compton Moller (MCM) runs, 4.5 uA
*25490 : HWP probably mixed up in the middle of run
*List of runs for which a rootfile does not exist !:
**23253
**23449
**23677 - 23765
------------------
*April 27, 2011 : Scalar banks added to the electron detector DAQ
