spot check of pattern for run 10090074
comparison of spinDB to Alice pattern used for ZDC analysis, table
Alice provided me with pol pattern for 1 run used by ZDC.
I compare the values , see attachment. Left side is my assignment, the right column is from you. We have exactly the same pattern except the abort gaps.
Looks like I use opposite convention for spin=2,8.
FYI, this is my convention, table 1 http://www.star.bnl.gov/protected/spin/balewski/2005-spinDB/definitions/
so my 8= means: B -, Y empty
my spin=2 means: B empty, Y=-
It does not change any asymmetry we compute, but would be good to converge on those.
Alice did not provided interpretation of her 2, 8.
For now I conclude we are consistent where it matters and I can assume I correctly computed the sign of AL
