HELP SECTION

TARPL
Type: Task
Use:  TARPL will write commands to a plot file or the TV to display
      a TARS output file.  Up to 30 RM spectra may be in the input
      text file, each of which may be plotted with a selected plot
      symbol (or omitted).  They may be connected by lines as well.

      TARPL will also plot the Q/U spectrum from a text file that is
      an input file to TARPL.  Note that there can only be one data
      set in such files.  TARS has no requirement that the data in
      the text file be in any specific order.  If the data are not
      in strict frequency order, leave VPARM 0 to avoid strange
      connecting lines.
Adverbs:
  USERID......The ID of the owner of the image.  Ignored
  INNAME......Image name (name).       Standard defaults.  The plot file
              is attached to this AIPS file which is otherwise ignored.
  INCLASS.....Image name (class).      Standard defaults.
  INSEQ.......Image name (seq. #).     0 => highest.
  INDISK......Disk unit #.             0 => any.
  INTEXT......Text file containing data to be input to or written by
              TARS (see explain for details).  The first line must
              be a comment with columns labeled K and RM is it is
              to be interpreted as an output file.
  APARM.......Self-scale examines only those spectra selected by RPARM
              and/or VPARM.
              (1,2) X plot range.  If APARM(2) <= APARM(1), self scale.
              (3,4) Y plot range for amplitude/real.  If APARM(4) <=
                    APARM(3), self scale,
              (5,6) Y plot range for phase/imaginary.  If APARM(6) <=
                    APARM(5), self scale.
              (7)   =  1 => Plot real and imaginary
                    =  2 => Plot real
                    =  3 => Plot imaginary

                    = 0  -> -1
              (8) > 0 -> Use lanbda^2 rather than frequency to plot
                   input files to TARS.
  RPARM.......(1-30) Plot symbol number for data of group 1-30, resp.
              You may have both a symbol and a line for each group
              0: No symbol plotted for this type
              1: Plus sign             12: Five pointed star
              2: Cross (X)             13: Star of David
              3: Circle                14: Seven-pointed star
              4: Box                   15: Eight-pointed star
              5: Triangle              16: Nine-pointed star
              6: Diamond               17: Ten-pointed star
              7: Pentagon              18: 11-pointed star
              8: Hexagon               19: 12-pointed star
              9: Septagon              20: 13-pointed star
              10: Octagon              21: 14-pointed star
              11: Nine-gon             22: Plus with gap
                                       23: Vertical line
                                       24: Cross (X) with gap
              If RPARM(i) is < 0, use abs (RPARM(i)) for phase only.
              If all RPARM and VPARM are zero, RPARM is set to 1 for
              all 30 values.
  VPARM.......(1-30) Line type number for data of group 1-30, resp.
              You may have both a symbol and a line for each group
              0: No line plotted for this group
              1: connected solid step line
              2: connected solid line
              3: dashed line, 1 break between points
              4: dashed line, 2 breaks between points
              5: and so on (VPARM(I)-2 breaks between points)
              If VPARM(i) is < 0, use abs (VPARM(i)) for all plots
              except phase.
  FACTOR......Symbol size multiplier; 0 -> 1.
  DO3COLOR....> 0 plot with colors (up to 4 groups use graphics planes
                  4, 3, 2, 1, > 4 groups use true grey-scale colors)
              = 2 plot with true grey-scale colors even with <= 4
                  groups
              <=0 plot without colors
              When plotting true colors, the first plotted group is
              plotted in red, the last in blue.  Thus if there are 4
              groups plotted in true color, they are assigned red,
              yellow, cyan, and blue, resp.
  LTYPE.......Labelling type, see HELP LTYPE for details:
              1 = border, 2 = no ticks, 3 or 7 = standard, 4 or 8 =
              relative to ref. pixel, 5 or 9 = relative to subimage
              (BLC, TRC) center, 6 or 10 = pixels.  7-10 all labels
              other than tick numbers and axis type are omitted.
             Less than 0 is the same except that the plot file
              version number and create time are omitted.
              Add n * 100 to alter the metric scaling.
  DOTV........> 0 => plot directly on the TV device, otherwise
              make a plot file for later display on one or
              more devices (including the TV if desired).
  GRCHAN......Graphics channel (1 - 7) to use for line drawing.
              0 => 1.

TARPL: Task to create a TARPL-plot extension file
DOCUMENTOR:
RELATED PROGRAMS: TKPL, TVPL, LWPLA, PLOTR

                           PURPOSE

     TARPL generates a plot extension file containing a TARPL plot,
its border, and labels.  The plot itself may be displayed on a
printer, TEK screen, or TV graphics channel by the tasks LWPLA, TKPL,
or TVPL respectively.

                          COMMENTS

Each data group begins with a line starting with ';   K' with the next
line giving a value of K equal 1.  The beginning line also gives
scaling and type information.  The task reads the data for the first
group until the end of file or another group start card is found.
then it reads the data for group 2 and so forth.  Which groups are
plotted is determined by RPARM and VPARM.

There may be 30 groups each of <= 2000 values.

The text file can contain other comment cards starting with an
character not blank or a number so long as they do not start with
semi-colon, 3 blanks, and the letter K (';   K').
