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:
AcdTileCount, AcdRibbonCount: Number of Tiles and Ribbons in the Event
AcdNoTop, AcdNoSideRowX [0-3]: Number of tiles in the event (for the top of the ACD and by row)
AcdActiveDistance3D: Distance to the closest edge of tile. Positive is inside tile, negative is outside tile.
AcdActDist3DTop, AcdActDist3DSideRowX [0-3]. Best active distance for the top and various side rows of the ACD
AcdRibbonActDist. Best Active distance to an Acd Ribbon
AcdCornerGap: Distance to closest gap along side of ACD, signed to match the direction of the overlap at the corner
