7 Conran_family internal parameters.

10 There are three Conran entries, CONRAN, CONRAQ, and CONRAS. CONRAN can
11 be invoked in two ways. One generates smoothed contours, the other
12 does not. CONRAQ is a quick version of the package which has a more
13 limited set of options than the other entries. CONRAS is the super
14 version of the package.
15 Parameters are set using the CONOP1, CONOP2, CONOP3, and CONOP4
17 entries. CONOP1 sets option switches, CONOP2 sets option switches and
18 option related integer arguments, CONOP3 sets option switches and
19 option related real arguments, and CONOP4 sets option switches and
20 option related character arguments. This man page provides a
21 functional overview of the parameters. See the man pages for the
22 CONOPx entries for precise information on how to make the option
23 setting calls.
24 All of the following parameters apply to normal, smooth, or super
26 versions of the package. The inclusive set of Conran parameters and
27 their switch defaults:

56
58 DEF This parameter provides a quick way to reset all parameters
59 to their default values.
60 EXT A parameter to set contour extrapolations. The default is
62 to only plot within the boundaries of the convex hull
63 defined by the user's data. To have the contours fill the
64 rectangular area of the frame, set the EXT switch ON.
65 GRI The parameter to display the grid. GRI is OFF by default.
67 Note: If GRI=ON, the virtual grid will be superimposed over
68 the contour plot. The X and Y tick intervals will be
69 displayed under the map only if PER=ON. (See parameter
70 PER)
71 ITP Set the interpolation scheme. There are two schemes --
73 C1 surfaces and linear. The C1 method (ITP=C1) takes
74 longer but will give the best results when the data is
75 sparse (less than 100 points). The linear method (ITP=LIN)
76 will produce a better plot when there is a dense data set.
77 The default is a C1 surface.
78 LAB This parameter determines whether to label the contours
80 (LAB=ON) or not (LAB=OFF). The default value is to label
81 the contours. (Does not apply to entry CONRAQ.)
82 LOT The parameter to list options on the printer. The default
84 value is to not display the options.
85 MES The parameter to plot a message. The default is that a
87 message is printed below the plot giving contour intervals
88 and execution time in seconds. If PER or GRI is ON, the
89 message also contains the X and Y tick intervals.
90 PDV The parameter to plot the input data values. The default
92 value is to not plot the input data.
93 PER The parameter to draw a perimeter. The default is to draw
95 a perimeter around the contour plot.
96 PMM The parameter to plot relative minima and maxima. The
98 default is to not plot them. (Does not apply to entry
99 CONRAQ.)
100 PSL The parameter which determines whether the outline of the
102 data shield will be drawn on the same frame as the contour
103 plot. The default is to not draw the shield. (Does not
104 apply to entry CONRAQ.)
105 REP The parameter indicating the use of the same data in a new
107 execution. The default value is to assume a new input
108 dataset.
109 SCA The parameter for scaling of the plot on a frame. This
111 parameter is ON by default.
112 TFR The parameter to advance the frame before triangulation.
114 The default value is TFR=ON, which means that the contours
115 and the triangles will be plotted on separate frames.
116 TOP The parameter to plot only the triangles. The default is
118 to plot contours, then triangles.
119 TRI The parameter to plot the triangulation. The default is
121 OFF and therefore the triangles are not drawn.
122
124 INT The parameter to determine line intensities for various
125 parts of the plot. Intensities vary from a high of 255 to
126 a low of 0. The default is high for all parts of the plot
127 except minor contour lines which are set to low.
128 LSZ This parameter determines the character size of contour
130 labels. The default value is 9, which results in label
131 characters of a size of 9./1023. NDC units. (Does not
132 apply to entry CONRAQ.)
133 NCP The parameter NCP controls the number of data points to be
135 used in the interpolation. Increasing NCP causes more of
136 the surrounding data to influence the point of
137 interpolation. In the case of linear interpolation NCP is
138 always 4. In the case of C1 interpolation, NCP can vary
139 from 2 to 25 with 4 as the default.
140 The interpolation option is selected using internal
142 parameter ITP.
143 SML This parameter specifies the character size of minimum and
145 maximum contour labels. The default value is 15, which
146 results in label character sizes of 15./1023. NDC units.
147 (Does not apply to entry CONRAQ.)
148 SPD The parameter for the size of the plotted input data
150 values. The default value is 8, which results in a data
151 value character size of 8./1023. NDC units.
152 SSZ The parameter to determine the resolution (number of steps
154 in each direction). The default is 40.
155 STL The parameter to determine the size of the main title
157 characters. The default value is 16, which results in
158 title character sizes of 16./1023. NDC units.
159
161 CHL This parameter determines how the high and low contour
162 values are set. The default is to compute the high and low
163 values from the input data.
164 CIL This parameter determines how the contour increment is set.
166 The default is to calculate the increment based on the
167 range of the input data.
168 CON This parameter determines how the contour levels are set.
170 The default is to have the program compute the contour
171 values and the number of contour levels.
172 DBP This parameter determines how the dash pattern break point
174 (BP) is set. The default is BP=0. (Does not apply to
175 entry CONRAQ.)
176 SDC The parameter to determine how to scale the data on the
178 contours. The default scaling is 1. (Does not apply to
179 entry CONRAQ.)
180 SLD This parameter allows for the entry of a bounding polygon
182 (shield). Only contours within the shield are drawn. The
183 default is no shield. (Does not apply to entry CONRAQ.)
184 TEN The parameter to determine the tension factor applied when
186 smoothing contour lines. The default value is 2.5. (Does
187 not apply to entry CONRAQ.)
188
190 DAS This parameter determines which contours are represented by
191 dashed lines. The default is to draw all contours as solid
192 lines. (Does not apply to entry CONRAQ.)
193 FMT A parameter which specifies a format for output of the data
195 values. If FMT=OFF, the default values of the format, the
196 number of characters in the format, and the length of the
197 output field described in the format, are (G10.3), 7, and
198 10, respectively.
199 TLE The parameter to place a title at the top of the plot. The
201 default value is no title.
