Union Issue

[ahmetcansansar]

In the ADL file below, we want to create an object called "lepDerive" that is union of "eleDerive" and "muDerive".

• "eleDerive" and "muDerive" are deriving from "eleA" and "muA" but we are not applying additional selections we are just selecting all. In this case, the code is crashing. Instead of selecting all when creating derived objects, if we apply a simple cut like "Pt > 0" then the code is executing without problems.

object muA : MUO
  select Pt(MUO) > 10

object muDerive : muA
  select ALL
  #select Pt(muA) > 0

object eleA : ELE
  select Pt(ELE) > 10

object eleDerive : eleA
  select ALL
  #select Pt(eleA) > 0

object lepDerive : Union(eleDerive, muDerive)

region test
  select ALL
  select Size(lepDerive) >= 1

Inconsistent Efficiency Calculation for goodLeps in BP_3

in adl file:

object goodPhotons take Photon

select Pt(Photon) > 10 # Require photon transverse momentum > 10 GeV select AbsEta(Photon) < 2.5 # Require photon to be within detector range (eta < 2.5)

object goodElectrons take Electron

select Pt(Electron) > 10 # Require Electron transverse momentum > 10 GeV select AbsEta(Electron) < 2.5 # Require Electron to be within detector range (eta < 2.5)

object goodMuons take Muon

select Pt(Muon) > 10 # Require Electron transverse momentum > 10 GeV select AbsEta(Muon) < 2.5 # Require Electron to be within detector range (eta < 2.5)

object goodLeps : Union( goodElectrons, goodMuons )

and the output is :

Description of the Issue: The reported number of goodLeps is inconsistent with the sum of goodElectrons and goodMuons in the event analysis.

Expected Behavior: The sum of goodElectrons (43,278) and goodMuons (63,494) is 106,772. This should match the number of goodLeps in the analysis. Observed Behavior: The reported number of goodLeps is 105,056, which is 1716 events fewer than expected. I think the Union function in cutlang.adl might not correctly handle.
