h2. Merit Tuple Variables
The complete list of merit tuple variables is here: [http://glast-ground.slac.stanford.edu/workbook/pages/gleamOvrvw/pr_summaryNtuples.htm]
Here are some plots for the most relevent ACD variables:
h3. AcdTileCount, AcdRibbonCount: Number of Tiles and Ribbons in the Event
!nTile.gif|thumbnail!
h3. AcdNoTop, AcdNoSideRowX \[0-3\]: Number of tiles in the event (for the top of the ACD and by row)
!nTileAll.gif|thumbnail!
h3. AcdActiveDistance3D: Distance to the closest edge of tile. Positive is inside tile, negative is outside tile.
!AcdDist.gif|thumbnail!
h3. AcdActDist3DTop, AcdActDist3DSideRowX \[0-3\]. Best active distance for the top and various side rows of the ACD
!AcdDist_All.gif|thumbnail!
h3. AcdRibbonActDist. Best Active distance to an Acd Ribbon
!AcdDist_rib.gif|thumbnail!
h3. AcdCornerGap: Distance to closest gap along side of ACD, signed to match the direction of the overlap at the corner
