TRUE) the outlines are drawn using a default projection—the size of the area plotted can be controlled by the SIZE parameter. Note, the facility to plot on an empty device is currently only available for two-dimensional regions specified using Parameter REGION.
"COFRAME(SKY,System=FK5)"would indicate that positions are specified in RA/DEC (FK5,J2000). The statement
"COFRAME(PIXEL)"indicates explicitly that positions are specified in pixel co-ordinates. The ARDFILE parameter is only accessed if Parameter REGION is given a null (

!) if the ARD region defined by Parameter ARDFILE is to be outlined. Suitable files can be created using the ATOOLS package.
TRUE. A SIZE value of
1.0causes the plot to be the same size as the Region being plotted. A value of
2.0causes the plot to be twice the size of the Region, etc.
A comma-separated list of strings should be given in which each string is either
an attribute setting, or the name of a text file preceded by an up-arrow character
Such text files should contain further comma-separated lists which will be read and interpreted in the
same manner. Attribute settings are applied in the order in which they occur within the list, with later
settings overriding any earlier settings given for the same attribute.
Each individual attribute setting should be of the form:
is the name of a plotting attribute, and
is the value to assign to the attribute. Default values will be used for any unspecified attributes. All
attributes will be defaulted if a null value (
!)—the initial default—is supplied. To apply changes of
style to only the current invocation, begin these attributes with a plus sign. A mixture of persistent
and temporary style changes is achieved by listing all the persistent attributes followed by a plus sign
then the list of temporary attributes.
See Section E for a description of the available attributes. Any unrecognised attributes are ignored (no error is reported).
bulge. The outline is drawn on the current graphics device and is drawn in alignment with the previous picture.
A DATA picture must already exist on the selected graphics device before running this command. An error will be reported if no DATA picture can be found.
The application stores a new DATA picture in the graphics database. On exit the current database picture for the chosen device reverts to the input picture.
