ETAordering

Asked by lyb

Dear Madanalysis experts,

From arXiv:1808.00480 (p79) we know that the objects could be ordered in normal mode by the increasing pseudorapidity named ETAordering. I want to know if it can be sorted according to the absolute value of the pseudorapidity，such as the option command for ABSETA. I tried ABSETAording is an invalid command.

Best regards,
Yao-Bei

Dear Yao-Bei,

What you asked is indeed not implemented. It is however very easy to hack. See the file
  tools/SampleAnalyzer/Commons/Service/SortingService.h
and the different PointComparison methods at the beginning of the file. One only needs to add absolute values in the "eta" one.

Cheers,

Benjamin
