xcolorcod (xcolorcod-1.30.1) [22.0.0-9173c7d25-20250127]

Parameters

This section documents the parameters recognized by this task (if any).

In determining the actual color of a pixel via the color curves the value range of the scalar column ecolumn is mapped onto the color table's level column ( $0\le level\le1$ ). The choice parameter ecolumnminmax selects one of three possible ways in which the dynamic value range $[min, max]$

of ecolumn is determined:

Parameter	Mand	Type	Default	Constraints
table	yes	table		name of existing table
The table that contains the event data - need to at least contain the columns named with the xcolumn, ycolumn, ecolumn parameters.
colortablechoice	no	string	internal	internal $\mid$ external
Choice parameter determining source of the color table that is to be used for the color coding. The value internal signifies that an internal table is to be selected via the colortable parameter. external activates the colortableset parameter.
colortable	no	string	heat	name of existing internal color table
If colortablechoice=internal the parameter signifies an internal color table that is the be used in the color-coding of the scalar event attribute. For a complete list of the available color tables invoke the task in dialog mode (xcolorcod -d) and select the choice widget labelled colortable.
colortableset	no	data set		name of exisiting data set
If colortablechoice=external the name of an external data set representing a color table that is to be used in the color coding of the scalar event attribute. The format must adhere to the specifications above.
invertcolortable	no	boolean	false	true $\mid$ false
With this boolean parameter the color curves in the color table can be inverted, i.e., a component that is associated with the scalar value level is associated with 1-level in the inverted case.
xcolumn	no	column	X	name of existing column in table
The name of the column that specifies the position of the event; passed to evselect as parameter xcolumn.
ycolumn	no	column	Y	name of existing column in table
The name of the column that specifies the y position of the event; passed to evselect as parameter ycolumn.
ecolumn	no	column	PI	name of existing column in table
The name of the column that specifies the scalar event attribute that is to be color-coded; passed to evselect as parameter zcolumn.
ecolumnminmax	no	string	actualminmax
actualminmax $\mid$ legalminmax $\mid$ explicitminmax

actualminmax	: from the data itself
legalminmax	: from the minimum/maximum legal values of the column given as column attributes TLMIN/TLMAX
explicitminmax	: by explicit parameters min and max

The ecolumn data value range $[min, max]$

will be linerly mapped onto the level range $[0, 1]$

scalenostringloglog $\mid$ lin Whether the intensity should be displayed linearly or logarithmically.
decadesnoreal4.0 $[-10, 20]$

Number of decades to be used if scale=log.
outputchoicenostringdatasetdataset $\mid$ ppmfile If set to dataset image is written to a data set whose name is given via parameter colorset. Otherwise, image is written in PPM format to standard file named via ppmfile.
colorsetnostringcolimg.dsname of data set The name of the data set the color image shall be written to if outputchoice=dataset. Depending on the value of ascube the data will either be written to three separate arrays corresponding to the red, green, and blue components or three slices of a 3-D data cube in the primary array, respectively. The data set can be read and the contents displayed with Ds9.
ppmfilenostringstdoutname of file If outputchoice=ppmfile the name of a PPM data file that the color image shall be written to. If ppmfile=stdout the data shall be written to standard output.
ascubenobooleanfalsefalse $\mid$ true Boolean parameter determining whether the red, green, and blue component images are to be written as three separate array extensions to the data set designated with colorset or as three slices of a single 3-dimensional data cube in the primary array.
