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
SPD=OFF SSZ=OFF STL=OFF
CONOP3 parameters (Switches & Real args) [7]
CHL=OFF CIL=OFF CON=OFF DBP=OFF
SDC=OFF SLD=OFF TEN=OFF
CONOP4 parameters (Switches & Character args) [3]
DAS=OFF FMT=OFF TLE=OFF
Parameters which are not available in CONRAQ, the quick version of the Conran_family:
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.
