    37 *View*  of the menubar, Data explorer can be toggled between Show and Hide by  
    38 clicking the menu *Show/Hide Data Explorer* . 
    39  
    40 *IMPORTANT!*  When Data explorer is hidden, all the data loaded will be sent  
    41 directly to the current active application, if possible. When data Explorer is  
    42 shown data go first to the Data Explorer for the user to handle them later.

    140  
    141 The 'view' option includes the axis scale short-cuts such as Linear, Guinier,  
    142 Cross-sectional (XC) Guinier, and Porod plot scale. For a proper data set,  
    143 these axis scales can be used to estimate Rg, Rod diameter, or Background of  
    144 neutron scattering data respectively (via 'Linear Fit'; see below). For a 2D  
    145 image, *Right click*  on the image to pop-up the context menu. Select to

    160 window appears. Change model initial parameters, data limits and hit *fit* 
    161 button. New parameters values are displayed and the line with the new 
    162 parameters is added to the plot. Especially for Guinier, XC Guinier, and 
    163 Porod plot scale, this 'Linear Fit' will provides Rg, Rod diameter, and 
    164 background, respectively. The following figure shows an example for the

    211 This feature allows you to perform different types of averages on your data,  
    212 and allows you to see what regions of the detector will contribute to the  
    213 average. The region to be averaged will be drown and can be modified by  
    214 dragging the lines around. 
    215  
    216 .. _How_to_Average: 
    217  
    218 How to Average 
    219 -------------- 
    220  
    221 Right click on 2D data for the context menu to appear. Select one type of  
    222 averages among *"sector [Q view]", "Annulus [Phi view]", "Box sum", "Box  
    223 averaging in Qx ", "box averaging on Qy","Perform circular Average".* 
    224  
    225 A slicer will appear except for *"Perform circular Average"*  that you can  
    226 drag by clicking on a slicer 's marker. When the marker is highlighted in red,  
    227 it means that the slicer can change size.You can also move some of the slicer  
    228 by simply drag its side when highlighted in red. the slicer size will be reset  
    229 to its previous size if the user try to select a region greater than the size  
    230 of the data. 
    231  
    232 The user can also select a region to average when a slicer has been selected  
    233 already by *right clicking*  on the context menu and selecting *Edit Slicer  
    234 Parameters* . The dialog window will appears and the user can enter values to  
    235 selected a region or selected numbers of points to plot *nbins* . 
    236  
    237 For *Box sum* , when the user selects this option, a new panel is created  
    238 containing the result of average of the sum of every pixels contains on that  
    239 data.The user can also enter values to select a region.

    265  
    266 Sector Average [Q View] 
    267 ----------------------- 
    268  
    269 This operation averages in constant q-arcs. The width of the sector is specified in 
    270 degrees (+/- delta phi) each side of the central angle (phi).

    273  
    274 Annular Average [Phi View] 
    275 -------------------------- 
    276  
    277 It performs an average between two q-values centered in (0,0), and averaged  
    278 over a width of a specified number of pixels. The data is returned as a  
    279 function of angle (phi) in degrees. Moving one circle of this slicer to  
    280 radius of zero corresponding to a circular averaging on radius qmax , the  
    281 outer circle. The angle zero starts from the positive x-axis direction.

    299 output is calculated from the constant bins with rectangular shape. The  
    300 resultant q values are nominal values, i.e., the central values of each bins
