HELP SECTION

TVLAYOUT
Type: Verb
Use:  TVLAYOUT will plot an antenna panel layout pattern in a graphics
      channel on the TV.  It does not erase the graphics channel, so
      do a GRCLEAR or TVLABEL first.  If there is more than one image
      (of a map) visible on the TV, the routine will ask the user to
      position the cursor on any part of the image he wishes labeled
      and then to press any button.  Note that this verb is for images
      of antenna surfaces only - it will do bad things on other kinds
      of images.  Note that this overlay option is also offered by
      plot tasks GREYS and KNTR.
Adverbs:
  GRCHAN......Graphics channel to use for the layout frawing.
              Unless changed by GWRIT or the .Xdefaults file (see HELP
              XAS), the normal color for channel 1 is yellow, 2 the
              previously familiar green, 3 pink, 4 cyan, 5 reddish, 6
              dark blue, 7 orange, 8 black.  0 -> 2.
  INFILE......' ' or 'VLA' -> use standard VLA layout pattern
              'VLBA'       -> use standard VLBA layout pattern
              Else look for a text file named INFILE.layout to
              generate a line plot showing the panel configuration.
              The panel layout file has format
                 n              ! card 1 gives number of circles
                 j   Rin   Rout ! n cards give number panels and their
                                  inner and outer radii in units of
                                  image
              any number of cards may follow and are ignored.  Thus
                       INFILE = 'MYWORK:MyVLA
              reads file "$MYWORK/MyVLA.layout" which might look like
                   6           ! number of panel rings
                  12   1.981   3.683
