CURSOR

        CLIC\CURSOR [mode]

    Call the interactive cursor, if  available  on  your  graphic  terminal.
    This  enables  you  to  measure  point coordinates and perform some data
    editing on the result of a PLOT command.

    After pressing any key, one of the data points is selected according  to
    the argument `mode'. In mode D the closest data point from the cursor is
    selected; in mode X (the default) the data point with closest X  coordi-
    nate  is selected; in mode Y the data point with closest Y coordinate is
    selected.

    The following actions are possible:

      - Press any key to get the coordinates of the selected point.

      - Press 'H' to display some header information of  the  selected  scan
        (as with LIST command).

      - Press 'K' to delete the selected point from the current plot buffers
        (type PLOT SAME to replot the buffers). This may be very  useful  to
        remove  corrupted  points from the buffers e.g. before fitting cali-
        bration curves.

      - Press 'N' to initiate a new range for  Ignore,  Tag,  and  Flag (see
        below).  This works only with time-like plots,  and  is to  be  used
        preferrably  with coordinates that are monotonous functions of  time
        (scan number, observation number, time, ...)

      -  Press  'I'  to ignore all scans in the current  range (initiated by
        'N').  This is equivalent to typing the IGNORE command for the  same
        scans.

      -  Press  'T'  to  tag  all scans in the current range  (initiated  by
        'N').  This is  equivalent  to typing the TAG command for  the  same
        scans.   You  will be prompted for a quality code in the range  0 to
        9 (see TAG command). The quality codes  are  stored  in  the  output
        file, which must be equal to the input file.

      -  Press  'F'  to  flag all records in the current range (initiated by
        'N').  You will be prompted for a list of flags (see FLAG  command).
        These flags will affect the baseline or antenna corresponding to the
        box you are pointing at. They will be stored  in  the  output  file,
        which must be equal to the input file.

      - Press 'E' to exit the cursor mode.
