Dear RGs Analysis Coordinator,<br>
<br>
in recent software meetings, it was agreed to create a new CCDB
table in the /runcontrol directory to store beam-related
information. <br>
The motivation is to store and make available to analyzers
information that may vary run by run and that is not stored in a
systematically consistent way across data sets and is not
programmatically accessible. Examples are:<br>
- the beam polarization value and uncertainty that should be
used in the analysis of a data set based on the results of the
Moeller measurements;<br>
- the beam energy if found to be different from the one reported
during data taking.<br>
<br>
To give the maximum flexibility, the CCDB table, named
/runcontrol/beam, would have 25 rows, to store up to 25
parameters, and 6 columns to store for each parameter:<br>
- 3 integer identifiers,<br>
- a name, defined as a string,<br>
- a value defined as a double,<br>
- the associated uncertainty, again as a double.<br>
Rows that not necessary will be filled with zeroes and empty
strings.<br>
<br>
Each Run Group is encouraged to exploit this table to store beam
parameters that are relevant for the analysis its data. To
facilitate the process of collecting the information and
uploading it to CCDB, Susan (in cc) has kindly agreed to work
with you to defined the list of parameters for your data and
collect the values for the relevant run ranges.<br>
<br>
Susan will be contacting you in the near future to start this
work.<br>
<br>
Let us know if you have any questions, comments, or suggestions.<br>
Best regards,<br>
Raffaella </div>
