When this button is selected, the 105 106 mouse cursor changes to an arrow. After the left mouse is pressed once, 106 a yellow background is shown for the excluded region and when the left mouse 107 a yellow background is shown for the excluded region, as is seen below. 108 When the left mouse 107 109 button is pressed a second time, the region is selected. 108 110 If the right mouse button is pressed instead, it resets the region selection. 111 <br clear=all> 112 <img SRC="exc3.gif" alt="EXCLEDT Screen snapshot"> 109 113 <br clear=all> 110 114 <img SRC="exc3a.gif" align=RIGHT alt="EXCLEDT Screen snapshot"> … … 123 127 <a href="#prompt">Options/Prompt on add/del</a>.)<br clear=all> 124 128 <P> 129 <br clear=all> 130 <H3>Keypad Shortcuts</H3> 131 <a name="manualzoom"></a> 132 <img SRC="mzoom.gif" align=RIGHT alt="EXCLEDT manual zoom"> 133 <IMG SRC="new.gif" HEIGHT=13 WIDTH=36 alt="New!"> 134 Zoom settings can also be entered manually by pressing the "Z" key. This 135 opens a dialog, as is shown to the right, where the x- or y-axis range 136 can be specified. Any value that is not specified is set to the maximum 137 or minimum for the entire dataset. It is possible to zoom further in using 138 the mouse, but to zoom out beyond the manual zoom limits, the "reset" button 139 on the manual zoom menu must be used. 140 <P> 141 <IMG SRC="new.gif" HEIGHT=13 WIDTH=36 alt="New!"> 142 If more than one histogram is available to plot, it is possible to cycle 143 between the histograms by pressing the "n" or "N" (for next) key. 144 <P> 145 <br clear=all> 146 <P> 147 <H3>Excluded Region/Simulation Range Buttons</H3> 125 148 <img SRC="exc4.gif" BORDER=3 align=right alt="EXCLEDT excluded regions snapshot"> 126 <H3>Excluded Region Buttons</H3>127 149 At the bottom of the window is a set of buttons with the minimum and maximum 128 150 limit on the data as well as a button for every excluded region.

Note that these values are always 186 displayed in the native units for the histogram (degrees, microseconds or Kev) 187 regardless of the setting for the x-axis units, since the step size is constant 188 in these native units. The data range is also shown in d-space and Q. 189 <P> 190 Note that it is not possible to edit the data range for 191 histograms with varying steps.
