| Variable | Definition |
| L2GMU_baseObj0 | (encoded) ID of the first base object used to make this object. |
| L2GMU_baseObj1 | ID of the second base object |
| L2GMU_baseObj2 | ID of the third base object |
| L2GMU_baseObj3 | ID of the fourth base object |
| L2GMU_baseObj4 | ID of the fifth base object |
| L2GMU_baseObj5 | ID of the sixth base object |
| L2GMU_eta | pseudorapidity of the object |
| L2GMU_ieta | Integral pseudorapidity of object. there are 160 bins with zero corresponding to -4 and 159 to +4. each bin steps .05 in eta. |
| L2GMU_iphi | Integral azimuthal angle of object. there are 160 bins with zero corresponding to zero and 159 to 2PI. each bin steps 2PI/160. |
| L2GMU_nMuons | number of muons in event(sum of all filters) |
| L2GMU_objID | the ID of the object. used by L2gblHead to tell which objects passed a script. there is a list there of all objects passing each script |
| L2GMU_phi | the azimuthal angle of the object |
| L2GMU_prompt | prompt value of the object. it is a kind of time of flight measurement. not yet used. |
| L2GMU_pt | transverse momentum of the object |
| L2GMU_quality | quality of the muon. not yet used. |
| L2GMU_sign | -1 = negative, 0 = unknown, +1 = positive |
