Conran_family_params - Includes a brief description of all
Conran_family internal parameters.
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:

EXT=OFF MES=ON REP=OFF
GRI=OFF PDV=OFF SCA=ON

Parameters which are not available in CONRAQ, the quick version of the
Conran_family:
DAS, DBP, LAB, LSZ, PMM, PSL, SDC, SLD, SML, TEN
- 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.
- 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.
- 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.)
- 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.
