NAME
Conran_family_params - Includes a brief description of all Conran_family internal parameters.
DESCRIPTION
There are three Conran 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.
Parameters are set using the CONOP1, CONOP2, CONOP3, and CONOP4 entries. CONOP1 sets option switches,
CONOP2 sets option switches and option related integer arguments, CONOP3 sets option switches and option
related real arguments, and CONOP4 sets option switches and option related character arguments. This man
page provides a functional overview of the parameters. See the man pages for the CONOPx entries for
precise information on how to make the option setting calls.
All of the following parameters apply to normal, smooth, or super versions of the package. The inclusive
set of Conran parameters and their switch defaults:
CONOP1 parameters (Switches) [16]
DEF (all options begin with defaults)
EXT=OFF MES=ON REP=OFF
GRI=OFF PDV=OFF SCA=ON
ITP=C1 PER=ON TFR=ON
LAB=ON PMM=OFF TOP=OFF
LOT=OFF PSL=OFF TRI=OFF
CONOP2 parameters (Switches & Integer args) [7]
INT=OFF LSZ=OFF NCP=OFF SML=OFF

CONOP3 parameters (Switches & Real args) [7]
CHL=OFF CIL=OFF CON=OFF DBP=OFF

DAS, DBP, LAB, LSZ, PMM, PSL, SDC, SLD, SML, TEN
Parameters which set option switches in calls to entry CONOP1:
DEF This parameter provides a quick way to reset all parameters to their default values.
EXT A parameter to set contour extrapolations. The default is to only plot within the boundaries
of the convex hull defined by the user's data. To have the contours fill the rectangular
area of the frame, set the EXT switch ON.
GRI The parameter to display the grid. GRI is OFF by default. Note: If GRI=ON, the virtual grid
will be superimposed over the contour plot. The X and Y tick intervals will be displayed
under the map only if PER=ON. (See parameter PER)
ITP Set the interpolation scheme. There are two schemes -- C1 surfaces and linear. The C1
method (ITP=C1) takes longer but will give the best results when the data is sparse (less
than 100 points). The linear method (ITP=LIN) will produce a better plot when there is a
dense data set. The default is a C1 surface.
LAB This parameter determines whether to label the contours (LAB=ON) or not (LAB=OFF). The
default value is to label the contours. (Does not apply to entry CONRAQ.)
LOT The parameter to list options on the printer. The default value is to not display the
options.
MES The parameter to plot a message. The default is that a message is printed below the plot
giving contour intervals and execution time in seconds. If PER or GRI is ON, the message
also contains the X and Y tick intervals.
PDV The parameter to plot the input data values. The default value is to not plot the input
data.
PER The parameter to draw a perimeter. The default is to draw a perimeter around the contour
plot.
PMM The parameter to plot relative minima and maxima. The default is to not plot them. (Does
not apply to entry CONRAQ.)
PSL The parameter which determines whether the outline of the data shield will be drawn on the
same frame as the contour plot. The default is to not draw the shield. (Does not apply to
entry CONRAQ.)
REP The parameter indicating the use of the same data in a new execution. The default value is
to assume a new input dataset.
SCA The parameter for scaling of the plot on a frame. This parameter is ON by default.
TFR The parameter to advance the frame before triangulation. The default value is TFR=ON, which
means that the contours and the triangles will be plotted on separate frames.
TOP The parameter to plot only the triangles. The default is to plot contours, then triangles.
TRI The parameter to plot the triangulation. The default is OFF and therefore the triangles are
not drawn.
Parameters of type INTEGER set in calls to entry CONOP2:
INT The parameter to determine line intensities for various parts of the plot. Intensities vary
from a high of 255 to a low of 0. The default is high for all parts of the plot except minor
contour lines which are set to low.
LSZ This parameter determines the character size of contour labels. The default value is 9,
which results in label characters of a size of 9./1023. NDC units. (Does not apply to entry
CONRAQ.)
NCP 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 internal parameter ITP.
SML This parameter specifies the character size of minimum and maximum contour labels. The
default value is 15, which results in label character sizes of 15./1023. NDC units. (Does
not apply to entry CONRAQ.)
SPD The parameter for the size of the plotted input data values. The default value is 8, which
results in a data value character size of 8./1023. NDC units.
SSZ The parameter to determine the resolution (number of steps in each direction). The default
is 40.
STL The parameter to determine the size of the main title characters. The default value is 16,
which results in title character sizes of 16./1023. NDC units.
Parameters of type REAL set in calls to entry CONOP3:
CHL This parameter determines how the high and low contour values are set. The default is to
compute the high and low values from the input data.
CIL This parameter determines how the contour increment is set. The default is to calculate the
increment based on the range of the input data.
CON This parameter determines how the contour levels are set. The default is to have the program
compute the contour values and the number of contour levels.
DBP This parameter determines how the dash pattern break point (BP) is set. The default is BP=0.
(Does not apply to entry CONRAQ.)
SDC The parameter to determine how to scale the data on the contours. The default scaling is 1.
(Does not apply to entry CONRAQ.)
SLD This parameter allows for the entry of a bounding polygon (shield). Only contours within the
shield are drawn. The default is no shield. (Does not apply to entry CONRAQ.)
TEN The parameter to determine the tension factor applied when smoothing contour lines. The
default value is 2.5. (Does not apply to entry CONRAQ.)
Parameters of type CHARACTER set in calls to entry CONOP4:
DAS This parameter determines which contours are represented by dashed lines. The default is to
draw all contours as solid lines. (Does not apply to entry CONRAQ.)
FMT A parameter which specifies a format for output of the data values. If FMT=OFF, the default
values of the format, the number of characters in the format, and the length of the output
field described in the format, are (G10.3), 7, and 10, respectively.
TLE The parameter to place a title at the top of the plot. The default value is no title.
