CAL Calibrations - electrons
700000691 is the first run of position scan cal-calibration runs. The position scans:
ydir:
700000703-712 (tower 2),
700000713-724 (tower 3),
x-dir:
700000725-737 (tower 2),
700000738-790 (tower 3)

(Dave Smith comments:-)It was the night of 27 to 28 July. CAL HI trigger never fired for the whole night, because the thresholds, which were supposed to be set to 1000 MeV (about 20 FHE DAC counts) were all set to 127 counts. This is being fixed right now (afternoon of28th).
To see the FHE DAC settings: from the eLog, for a given run, click on the "config" report link, and way down in the .pdf file there are tables of CAL GCFE settings.
Baseline configuration - electrons
These runs were taken with baseline configuration. Time settings for those may not be optimal, please verify that before you do your anlaysis. We need to verify if the configurations agree with the description . CAL_HI may not be enabled for these runs

ACD timed in with CAL and TKR - electrons
These runs were used to time in the ACD. CAL_HI now is correctly enabled from run 700000820.
700000821 : 90 degrees - delay is 8 ticks for external trigger
700000822 : 90 degrees - delay is 4 ticks for external trigger
ACD timed in with CAL and TKR - pions
These runs were used to time in the ACD.
700000821 and 7000000822
Run 700000825

Packet error events
These runs need to be studied to cverify events begore and after errors

ACD Calibrations with ACD timed in
Run 700000829 BT12 ACD pedestal run Tile 4 far from the table - this pedestal reference run
Run 700000830 BT12 ACD run Tile 4 according to calibration setting
Run 700000831 BT12 ACD run Tile 3 according to calibration setting has 10% packet errors
Run 700000832 BT12 ACD run Tile 2 according to calibration setting has 30% packet errors
Run 700000833 BT12 ACD run Tile 1 according to calibration setting has 30% packet errors
Run 700000834 BT12 ACD run Tile 0 according to calibration setting has 30% packet errors
High Voltage Set to 760 - too high pulse heights from tiles 0 and 1
Created BT12 which is same as BT1 but with Zero suppression off for Alex to see pedestals. See configuration for details.
These are calibration runs for ACD tiles
