---++++ List of Shift Histograms

---++++ Barrel Occupancy Wheel vs Sector*


| *RPC Barrel Occupancy |
| RPC Barrel Occupancy summary view; In good case colors must be more or less same everywhere (It means we have uniform Occupancy in the RPC Barrel by Wheels). If you see different color somewhere on the histogram check corresponding sector in order to understood which chamber is producing wrong color. not welcome colors is white and red. white means Occupancy from corresponding sector is zero. Red - corresponding sector is doing lot of noise. (go and see coresponding histogram SectorOccupancy_Wheel_X_Sector_Y under RPC/RecHits/Barrel/Wheel_X/SummaryBySectors/) |^| <img src="https://twiki.org/p/pub/Main/DavidLomidze/BarrelOccupancy.png" onclick="this.src='https://twiki.org/p/pub/Main/DavidLomidze/BarrelOccupancy_good_ref.png'" ondblclick="this.src='https://twiki.org/p/pub/Main/DavidLomidze/BarrelOccupancy.png'" /> <br/> |<img src="https://twiki.org/p/pub/Main/DavidLomidze/BarrelOccupancy_Bad.PNG" onclick="this.src='https://twiki.org/p/pub/Main/DavidLomidze/BarrelOccupancy_Bad_ref.png'" ondblclick="this.src='https://twiki.org/p/pub/Main/DavidLomidze/BarrelOccupancy_Bad.PNG'" /><br/>dblclick - back) |

| *<a name="RPC Wheel 1D Occupancy"></a> RPC Wheel 1D Occupancy *|
| Wheel Occupancy Summary view; Wheel Occupancy by Sectors. good case - more or less same occupancy from all sectors, best case when you are seeing uniform histogram. If you are seeing zero entry for a bin or lots of entry's in a bin (not uniform histogram) please check gaz, LV, HV or check if strip masking is well done for problematic sector |^| <img src="https://twiki.org/p/pub/Main/DavidLomidze/1DOccupancy_Bad.jpg" onclick="this.src='https://twiki.org/p/pub/Main/DavidLomidze/1DOccupancy_Bad_ref.jpg'" ondblclick="this.src='https://twiki.org/p/pub/Main/DavidLomidze/1DOccupancy_Bad.jpg'" /> | | <img src="https://twiki.org/p/pub/Main/DavidLomidze/1DOccupancy_Good.PNG" onclick="this.src='https://twiki.org/p/pub/Main/DavidLomidze/1DOccupancy_Good_ref.PNG'" ondblclick="this.src='https://twiki.org/p/pub/Main/DavidLomidze/1DOccupancy_Good.PNG'" /> |

|*RPC Sector Occupancy*|
| Sector summary view; the histogram is showing Sector Occupancy Chamber vs Strip, in good case all the strips must show more or less uniform occupancy, if you see missing chambers or missing strips (white space) inform RPC Online shifter, white space means no signal from Chamber or from Strip. Red color means corresponding stip(s) is noisily |^| <img src="https://twiki.org/p/pub/Main/DavidLomidze/SectorOccupancy_Good.PNG" onclick="this.src='https://twiki.org/p/pub/Main/DavidLomidze/SectorOccupancy_ref.PNG'" ondblclick="this.src='https://twiki.org/p/pub/Main/DavidLomidze/SectorOccupancy_Good.PNG'" /> | | <img src="https://twiki.org/p/pub/Main/DavidLomidze/SectorOccupancy_Bad.jpg" onclick="this.src='https://twiki.org/p/pub/Main/DavidLomidze/SectorOccupancy_Bad_ref.jpg'" ondblclick="this.src='https://twiki.org/p/pub/Main/DavidLomidze/SectorOccupancy_Bad.jpg'" /> |
| If anything appears RED there, shifter should check histograms in Shifter Layout. |
