":"will display details of the current co-ordinate Frame). The position should be supplied as a list of formatted axis values separated by spaces or commas. See also Parameter USEAXIS. The current co-ordinate Frame can be changed using task WCSFRAME.
"Error"is equivalent to
"10.2"means 10.2 arcseconds,
"30:0"would mean 30 arcminutes, and
"1:0:0"would mean 1 degree. If the current co-ordinate Frame is not a SKY Frame, then the diameter should be specified as an increment along Axis 1 of the current co-ordinate Frame. Thus, if the current Frame is PIXEL, the value should be given simply as a number of pixels.
TRUEvalue is supplied, the constant value is assigned to the inside of the circle. Otherwise, it is assigned to the outside.
!) propagates the title from the input NDF to the output NDF.
Its integer index within the current Frame of the input NDF (in the range 1 to the number of axes in the current Frame).
Its Symbol string such as
A generic option where
"SPEC" requests the spectral axis,
"TIME" selects the time axis,
"SKYLAT" picks the sky longitude and latitude axes respectively. Only
those axis domains present are available as options.
A list of acceptable values is displayed if an illegal value is supplied. If a null (
value is supplied, the axes with the same indices as the two used pixel axes within the
NDF are used.
All non-complex numeric data types can be handled.
