Initial Calibaration    

 This calibration was done with the 200 GeV proton-proton data collected in 2012. The calibration trees are backed up on HPSS and can be found here:

Electron calibration

Getting Started

1) The code needed to perform the gain calibrations can be checked out from CVS and compiled. In your working directory, do:

Once the ped/stat tables have been generated, they must be QAed.  I do the QA in two parts:

Once the ped/stat tables have been QAed satisfactorily, the values need to be uploaded to the database. 

Getting Started

Here you will find the calibration procedure for the BTOW (as of 2013). 

Additional documentation about BTOW gain calibrations in previous years can be found here: 

Yearly Timestamp Initialization

==========

We started this task by looking at BSMD in Run 10 with some MuDst files, and found the pedestals probably need to be QA-ed as well.

All the details of the mapping problem can be found in this ticket.  This page is a summary of the problem, solution, and

In essence, the 200 GeV status tables were calculated the same way as the 500 GeV tables were.  Please see

The Run 9 BSMD absolute calibration was made using few-GeV TPC-identified electrons from pp500 running, and has two pieces.  The first is a new CALIBRATION table in the database whic

I selected 634 runs for calibration from the Run 9 production, processing over 300M events.

Here (below) are the BSMD FEE repair record spreadsheets from Phil Kuczewski.

The one with label "BEMC_FEE_Repairs-2010.xls" is most recent, including repairs in 2010

I recalculated the Barrel calibration using the latest L2W production, which relies on the latest TPC calibration.
