Examining and Editing ASCII data
The EXAMINE WIDGET.
The EXAMINE WIDGET provides selectors for viewing actual data values plus other kinds of data such as a ray by ray inventory of all the rays in the sweep, a listing of all the relevant DORADE headers, a list of all the editing operations that have been performed on the current sweep plus a means to examine and modify the individual cell values. All lists and data are displayed in a companion widget call the DATA VIEW widget. DORADE descriptor information is for the final ray in the DATA VIEW.
Clicking in the color display when the EXAMINE WIDGET is up and Examine data is selected will cause the data display to be centered on the clicked location.
Clicking in the DATA VIEW list when Examine data is selected will cause the modification selected in the EXAMINE CHANGE widget to be performed.
The EXAMINE FORMAT widget.
The EXAMINE FORMAT widget controls the display of radar data by allowing users to specify the format of the numbers, the number of rays, the number of cells, which variables and the ray and cell of the upper left corner of the display. The numbering of rays and cells begins at zero.
The EXAMINE SCROLL widget.
The EXAMINE SCROLL widget controls shifting the display up or down by the number in the scroll inc and left or right by one ray.
The EXAMINE CHANGE widget selects the type of change, undoes the last change, clears all changes, and allows changing of a selected cell to a specific value.
It is IMPORTANT to remember that the changes are occuring only to a list of the data values kept in memory. The user needs to click in the COMMIT CHANGES button to cause changes in the sweep file on the disk and Solo will complain if the user tries to change the location of the DATA VIEW when there are changes that have not been committed.
change count list the number of outstanding changes.
clear changes undoes all outstanding changes.
undo undoes the last change.
change to causes the cell value to be replace with the value in the box to the right of change to.
-1 fold selects the type of modification to the data that will result in one Nyquist interval being subtracted from the clicked cell. See change Nyquist Velocity for information on how to temporarily change the Nyquist Velocity. See changing header values for information on permanently modifying the Nyquist Velocity.
+1 fold selects the type of modification to the data that will result in one Nyquist interval being added to the clicked cell.
delete causes the cell value to be replaced with a bad data flag.
remove ground speed causes the contribution of the aircrafts motion to the velocity to be removed from the clicked cell.
delect ray causes the ray containing the clicked cell to be removed from the sweep file.
- fold ray causes the Nyquist interval to be subtracted from the entire ray. Clicking in the same cell consecutively subtracts a Nyquist interval for each click. Clicking two different cells consecutively in the same field will cause the two clicked cells and all the cells in between to have a Nyquist interval subtracted from them.
+ fold ray causes the Nyquist interval to be added to the entire ray.
COMMIT CHANGES must be clicked when the user is satisfied with all the changes in order for the changes to become permanent. Solo will complain if the user tries to change to location of the DATA VIEW when there are changes that have not been committed.
