NAME
       CONRAS - draws a two dimensional contour map from irregularly distributed data.  This is the super
       version of the Conran_family.


STATUS
       CONRAS is approaching obsolescence.  If you have available an interpolation package which can do a random
       to gridded interpolation equal to that built into the Conran_family, then we recommend that you grid your
       dataset and use the Conpack utility instead.  Refer to the conpack and conpack_params man pages as well
       as the NCAR Graphics Contouring and Mapping Tutorial.


SYNOPSIS
       CONRAS (XD,YD,ZD,NDP,WK,IWK,SCRARR)


DESCRIPTION
       XD          Input, real array -- of dimension NDP containing the X coordinates of the data points.

       YD          Input, real array -- of dimension NDP containing the Y coordinates of the data points.

       ZD          Input, real array -- of dimension NDP containing the data values at the points.

       NDP         Input, integer -- is the number of data points to be contoured.  NDP must be 4 or larger.

       WK          Input, real array -- workspace of dimension 15*NDP.

       IWK         Input, integer array -- workspace which must be dimensioned at least IWK((27+NCP)*NDP).

                   The parameter NCP controls the number of data points to be used in the interpolation.
                   Increasing NCP causes more of the surrounding data to influence the point of interpolation.
                   In the case of linear interpolation NCP is always 4.  In the case of C1 interpolation, NCP
                   can vary from 2 to 25 with 4 as the default.

                   The interpolation option is selected using parameter ITP.  See the conran_family_params man
                   page for a description of all internal parameters.

       SCRARR      Real work array of dimension at least (RESOLUTION**2) where RESOLUTION is 40 by default.

                   Alternate resolutions are set using parameter SSZ.  See the conran_family_params man page.


USAGE
       The contours will be drawn as smoothed dashed or solid lines using splines under tension.  There may be
       characters along the lines.  Crowded contour lines may be thinned.  Many other options are available
       through the use of internal parameters.  See the conran_family_params man page.

       Quick and standard-and-smooth versions of the Conran_family are also available through entries CONRAQ and
       CONRAN, respectively.


EXAMPLES
       Use the ncargex command to see the relevant example tconas.


ACCESS
       To use CONRAS, load the NCAR Graphics libraries conras, dashsupr, ncarg, ncarg_gks, and ncarg_c,
       preferably in that order.

       The conras and dashsupr libraries are not loaded as part of the normal NCAR Graphics installation.  They
       can be loaded by the user directly, or loaded implicitly through the use of the -super option of the
       ncargf77 command.

       SUPER     Command: "ncargf77 -super mycode.f"


MESSAGES
       See the conran_family man page for a description of all Conran_family error messages and/or informational
       messages.
