NAME

       Conran_family - is a set of two dimensional contour mapping routines for irregularly
       distributed data.

       There are three Conran_family entries, CONRAN, CONRAQ, and CONRAS.  CONRAN can be invoked
       in two ways.  One generates smoothed contours, the other does not.  CONRAQ is a quick
       version of the package which has a more limited set of options than the other entries.
       CONRAS is the super version of the package.

STATUS

       The Conran_family 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

       CONRAN - Provides the standard and smooth versions for contouring of irregularly gridded
       data.

       CONRAQ - Provides the quick form of the package.  It does not have as many available
       options as the other entries.

       CONRAS - This is the super version of the package.  Not only does it smooth and label
       contour lines, it can also reduce line crowding.

       CONOP1 - Sets values of internal parameters of type logical.  Specifically, CONOP1 is used
       to turn options "OFF", or "ON".

       CONOP2 - Sets values of internal parameters of type integer.

       CONOP3 - Sets values of internal parameters of type real.

       CONOP4 - Sets values of internal parameters of type character.

ACCESS

       There are three entries in the Conran_family which create contour plots: CONRAQ (quick),
       CONRAS (super), and CONRAN (standard and smooth.)

       To use standard CONRAN, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c,
       preferably in that order.  To run any of the other three options (quick, super, or
       smooth), one or more additional libraries is needed as follows:

       quick -- additionally load the conraq library.

       smooth -- additionally load the dashsmth library.

       super -- additionally load the conras and dashsupr libraries.

       These libraries can also be implicitly loaded by using the -quick, -smooth, or -super
       option of the ncargf77 command.  For example, to run a code called mycode.f which has one
       or more calls to a Conran_family entry, issue one of the commands:

       QUICK     Command: "ncargf77 -quick mycode.f"

                 mycode.f has one or more calls to entry CONRAQ.

       NORMAL    Command: "ncargf77 mycode.f"

                 mycode.f has one or more calls to entry CONRAN.

       SMOOTH    Command: "ncargf77 -smooth mycode.f"

                 mycode.f has one or more calls to entry CONRAN.

       SUPER     Command: "ncargf77 -super mycode.f"

                 mycode.f has one or more calls to entry CONRAS.

                 Warning:  mycode.f can only call one of the three entries, CONRAQ, CONRAN, or
                 CONRAS.

MESSAGES

       Error messages generated by CONRAN routines include:

       CONCLS    CONSTANT INPUT FIELD
                 The input data all has a constant value.  This may indicate that the data has
                 not been input correctly in the user program.

       CONDRW    CONTOUR STORAGE EXHAUSTED
                 This error is trapped and nullified by CONRAN.  It serves to signal the user
                 that a contour level may not be complete.

       CONOP     UNDEFINED OPTION
                 The parameter name has either been misspelled in a CONOP call, or an out of
                 range parameter value has been specified.  This message can be generated by
                 CONOP1, CONOP2, CONOP3, or CONOP4.

       CONOP3    ILLEGAL USE OF CON OPTION WITH CIL OR CHL OPTIONS
                 Review the definitions of these three parameters using man page
                 conran_family_params.

       CONOP3    NUMBER OF CONTOUR LEVELS EXCEEDS 30
                 Reduce the requested number of contour levels specified by parameter CON to 30
                 or less.

       CONRAN    INPUT PARAMETER NDP LT NCP
                 NDP is the total number of input values for contouring.  NCP is the number of
                 points used for partial derivative estimation.  NCP cannot exceed NDP.  This
                 error message also occurs in CONRAS and CONRAQ.

       CONRAN    NCP LT 2 OR GT NCPSZ
                 The legal value of NCP must be between NCPSZ (dimension size allowed) and 2.
                 This error message also occurs in CONRAS and CONRAQ.

       CONSTP    ASPECT RATIO OF X AND Y GREATER THAN 5 TO 1.
                 (This error may cause a poor quality plot.  Usually this can be fixed by
                 multiplying X or Y by a constant factor.  If this solution is unacceptable then
                 increasing internal parameter SSZ to a very large value may help.  Note:  This
                 can be expensive.)

       CONTNG    ALL COLINEAR DATA POINTS
                 Indicates that the input data set to be contoured all lies along a straight
                 line.  Thus, triangulation cannot occur.

       CONTNG    IDENTICAL INPUT DATA POINTS FOUND

                 The errors listed above are defined as recoverable errors should the user wish
                 to use them in that fashion.  The documentation on the ERPRT77 package explains
                 how to recover from an error.
