How To use Wedge Display





Wedge Display

Introduction to Wedge Display:

WedgeDisplay is a display to show CES wire/strip and CPR wire signals together with Central Calorimeter and CDFTrack signals. It is opened from a pop up menu attached to the Lego tower of the Calorimeter Lego plot, CES display and CALORIMETER display, or the towers in COT display.

To pop up the menu in the case of Calorimeter Lego plot, or from CES display and CALORIMETER display push Pick or Tower button of the display frame, and move the cursor to the Lego tower. When the cross cursor changes to the hand cursor, press the right mouse button, then the pop-up menu is shown. When the PopUpWedgeDisplay in the pop-up menu is selected, the Wedge Display for the selected tower is shown in the new window. Please note that if the left mouse button is pressed, the color of the lego tower changes to red and you can not show the pop-up menu for the Wedge Display any more unless you go to the next event. If the tower in the Plug Calorimeter is selected, no display is shown.

To open WedgeDisplay from COT Display: click right mouse button on the tower (in the HIT mode), choose PopUpWestWedgeDisplay or PopUpEastWedgeDisplay.

Objects on the display:

Following graphic objects are drawn on the display:

   Green histogram:  CES strip/wire pulse height
   Blue histogram :  CPR wire pulse height
   Purple Lego    :  CEM pulse height
   Blue Lego      :  CHD pulse height
   Green line     :  CES Wire and Strip cluster position
   Blue line      :  CPR Wire cluster position
   Khaki line     : CDF Track position

CES/CPR data are taken from SortableBank and calibration constants are applied to convert it to energy. For Lego's, ADC data of each PMT's are taken from CalData bank and scaled according to the summed energy of the tower. Pulse height of histograms and Lego's are scaled automatically to the highest pulse height bin. Lines overlaid on the lego plot are position of clusters such as CES strip/wire and CPR wire. Track based clusters are used for the display. Note that wire signal provides phi position, while strip signal provides eta position. The intersetion of the vertical Khaki line with the E=0 plane indicates the position of the CDF Track extrapolarted to the CES. All CDFTracks to the Wedge are shown independently with the association with CES/CPR clusters.

Flags for display and information shown on the display are changed depending on which Select Buttons is pressed.

If View button is pressed, the cursor is always the cross. When right mouse button is pressed at anywhere in the display pad, the pop-up menu for the Wedge Display is shown. >From the menu, use can turn on/off display of clusters, axes and text messages. Print menu for CES/CPR cluster is also included. The initial parameters for them are taken from .envrc file similar to the other evd parameters and can be saved in the file at the end of evd program. The name of parameters, meanings and default values are described here.

If Pick, Tower, or Cluster button is pressed, the cursor changes to the hand if the mouse is on a display object such as histograms and clusters. The object information is shown on the second bottom line of the display window. The objects information includes bin number, bin contents, linked track ID, Pt, eta, etc depending on the objects. If the right mouse button is pressed when the cursor is the hand, the pop-up menu for the object is displayed, from which track and cluster information can be printed in the case of CES/CPR clusters and the histogram can be shown in the case of CES/CPR histograms. The histogram is the same histogram as shown by histogram menu of Lego Display or CES Display.

On the top of the pad, run number, event number and other information about the event are shown. Next line shows the East or East wedge and module number. Module number runs from 0 to 23, corresponding to the azimuthal angle location of the wedge.

If ShowLegend flag is set, the signal information is printed on the top-right corner of the canvas. The information includes the channel number and the pulse hight of the maximum channel of CES strip and CES/CPR wire, the cluster position and linked CDF track ID. The track is indicated as muon if it is flaged as muon.

Buttons and Slide Bars:
Buttons and slide bars on the display frame work as well as Lego plots, excepts next and previous. If next or previous button are pressed all WedgeDisplay frames are closed since new event may not have entry in the current wedge.
