The image is actually shown in zoom only when the menu selection is not going on. Thus, the image is zoomed during cursor-value, zooming and window and box setting. C----------------------------------------------------------------------- TVZOOM This option lets you set the TV zoom magnification factor and to set the point about which the zoom takes place. The cursor points at the zoom center which will be shifted to the center of the screen. A hit on buttons A or B increments the magnification factor and on button C decrements the magnification factor in a circular fashion. Hit button D to exit. Instructions appear on the message screen. C----------------------------------------------------------------------- SET WINDOW This option allows you to limit the editing and display to a rectangular portion of the full plot. First move the cursor to set the bottom left corner of the plot, then hit button A or B to begin setting the upper right corner. Hit buttons A or B to swith corners. Hit buttons C or D to return to the menu mode (after the selected window is displayed). C----------------------------------------------------------------------- RESET WINDOW This option resets the window to include the full plot in the display and editing. The full plot is re-displayed. If it does not all fit on the TV (at full size), then the plot is shown with averaged pixels and you are told to select a sub-image to display and edit. C----------------------------------------------------------------------- FLAG POINT This option allows you to flag pixels not already flagged. Move the cursor to the pixel to be flagged - the coordinates of the pixel in both pixel and physical units and the number of points included in the pixel are shown in the upper left. To flag a point hit button A, B, or C. The pixel will change color after which you may flag more pixels (buttons A or B) or select a new menu option (button C). Button D allows you to return to the menu without flagging the current point. C----------------------------------------------------------------------- FLAG AREA This option allows you to flag pixels within rectangular areas. Move the cursor to select the bottom left pixel of the area, then hit button A to set the top right corner of the area. Hit button A as needed to reset the opposite corners. Hit button B or C to flag all unflagged pixels in the rectangle. The pixels will change color after which you may set a new rectangle (button B) or select a new menu option (button C). Button D allows you to return to the menu without flagging the current rectangle. C----------------------------------------------------------------------- FLAG FAST This option allows you to flag individual pixels rapidly. Move the cursor to the first point to be flagged and hit one of buttons A, B, or C. Any further button hit will return to the main menu. Any unflagged pixel selected by the cursor (remember - left mouse button depressed or click it on the point) will be flagged, changing color as it is flagged. C----------------------------------------------------------------------- FLAG FAT This option allows you to flag a circular area around individual pixels rapidly. Move the cursor to the first point to be flagged and hit one of buttons A, B, or C. Any further button hit will return to the main menu. Any unflagged pixel within a radius of BPARM(9) plot pixels of the pixel selected by the cursor (remember - left mouse button depressed or click it on the point) will be flagged, changing color as they are flagged. BPARM(9) may be changed interactively with the WIPER SET and WIPER SIZE operations. C----------------------------------------------------------------------- FLAG BASELIN This option allows you to type in 2 numbers giving the two antennas of the baseline you wish to flag. If one of the numbers is 0, all baselines to the second number will be flagged. This operation enters the desired baseline(s) into a list first and then examines all plotted points to find any that are affected by the baseline(s). The attaced baseline info is modified to record the flagging and and if there remain no unflagged baselines attached to the point, its color is changed to that used for flagged data. C----------------------------------------------------------------------- UNFLAG POINT This option allows you to unflag pixels that are already flagged. Move the cursor to the pixel to be un flagged - the coordinates of the pixel in both pixel and physical units and the number of points included in the pixel are shown in the upper left. To flag a point hit button A, B, or C. The pixel will change color after which you may unflag more pixels (buttons A or B) or select a new menu option (button C). Button D allows you to return to the menu without unflagging the current point. C----------------------------------------------------------------------- UNFLAG AREA This option allows you to unflag pixels within rectangular areas. Move the cursor to select the bottom left pixel of the area, then hit button A to set the top right corner of the area. Hit button A as needed to reset the opposite corners. Hit button B or C to unflag all flagged pixels in the rectangle. The pixels will change color after which you may set a new rectangle (button B) or select a new menu option (button C). Button D allows you to return to the menu without unflagging the current rectangle. C----------------------------------------------------------------------- UNFLAG FAST This option allows you to UNflag individual pixels rapidly. Move the cursor to the first point to be unflagged and hit one of buttons A, B, or C. Any further button hit will return to the main menu. Any flagged pixel selected by the cursor (remember - left mouse button depressed or click it on the point) will be unflagged, changing color as it is unflagged. C----------------------------------------------------------------------- UNFLAG FAT This option allows you to unflag a circular area around individual pixels rapidly. Move the cursor to the first area to be unflagged and hit one of buttons A, B, or C. Any further button hit will return to the main menu. Any flagged pixel within a radius of BPARM(9) plot pixels of the pixel selected by the cursor (remember - left mouse button depressed or click it on the point) will be flagged, changing color as they are flagged. BPARM(9) may be changed interactively with the WIPER SET and WIPER SIZE operations. C----------------------------------------------------------------------- UNFLAG BASEL This option allows you to type in 2 numbers giving the two antennas of the baseline you previously did a FLAG BASELIN upon and which you now wish to undo. If one of the numbers is 0, all baselines to the second number will be unflagged. This operation removes the desired baseline(s) from the flagged list first and then examines all plotted points to find any that are affected by the baseline(s). The attaced baseline info is modified to record the unflagging and and if there are now unflagged baselines attached to the point, its color is changed to that used for good data. C----------------------------------------------------------------------- WIPER SET This option allows you to change the size of the "fat" wiper interactively. A horizontal line is drawn on the TV and labeled from 0 to 12. In addition, the current wiper size is shown at the upper left and as a circle somewhere near the center of the screen. The horizontal position of the cursor controls the wiper size. Hit any button to return to the main menu. C----------------------------------------------------------------------- WIPER SIZE This option allows you to change the size of the "fat" wiper interactively. The current wiper size is shown at the upper left and as a circle somewhere near the center of the screen. The position of the cursor controls the wiper size. Hit any button to return to the main menu. C----------------------------------------------------------------------- ABORT This option tells WIPER to stop now, ignoring any flagging which may have been done. No flag table is written. C----------------------------------------------------------------------- EXIT This option tells WIPER to terminate interactive operations. It then redoes the plot operation decrementing the counts in each pixel. If a pixel has been flagged then a line is written to the output flag table. The output flag table starts with the input flag table, with the copy operation being done only if there are flagged data. C-----------------------------------------------------------------------
