[G12] dc efficiency

[Saini, Mukesh]

Hi All,

It could be the RunIndex or even the run number. 

For RunIndexg12 at least, constants for all the runs are the same.

If one needs to use a special RunIndex for any/test reasons, just verify that their RunIndex links back to the correct GPP DC efficiency constants using the "ItemValueID" field for all the DC sectors. 

The link below shows "itemValueID=88" for GPP -> DC_WIRE -> sector6. 

http://clasweb.jlab.org/cgi-bin/caldb/cq.pl?button=Run+Ranges&runMin=1&runMax=57400&system=GPP&subsystem=DC_WIRE&item=sector6&run=&itemValueId=&date=&runIndexTable=calib_user.RunIndexg12&hostname= 
 
As long as the itemValueID matches for all of the sectors for the Run Number you are using, the RunIndex being used has the correct DC efficiency maps for GPP.

Regards, 
Mukesh.

The dc efficiency is documented at
https://clasweb.jlab.org/rungroups/g12/wiki/index.php/Wiremaps

There is a link to the maps there as well. In any case, Maurizio is
the expert on this, and I think he helped Mukesh do this.

As far as I can tell, it looks like everything was done properly.
Maybe some has not run gpp properly in their simulation. Or maybe the
gpp map for the wire efficiency for certain runindex in the database
that some might be using could somehow be messed up.
