-
XMIN = _REAL (Read and Write)
-
The world coordinate of the left-hand edge of the plot.
The application will determine the value.
-
XMAX = _REAL (Read and Write)
-
The world coordinate of the right-hand edge of the plot.
The application will determine the value.
-
YMIN = _REAL (Read and Write)
-
The world coordinate of the lower edge of the plot.
The application will determine the value.
-
YMAX = _REAL (Read and Write)
-
The world coordinate of the upper edge of the plot.
The application will determine the value.
-
PROJECTION = _CHAR (Read and Write)
-
The geometry to be used for plotting the data. This is
explained in more detail in the section on projections.
Allowed values: "NONE", "TAN", "SIN", "ARC", "GLS", "AITOFF",
"MERCATOR" and "STG".
[The value of the global parameter PONGO_PROJECTN is used. If
PONGO_PROJECTN is not defined, the default value "NONE" is
used.]
-
RACENTRE = _CHAR (Read and Write)
-
The centre of the projection in RA (i.e. the angle must be
specified as hh:mm:ss.sss). This parameter is only required for
PROJECTION values other than "NONE".
[The value of the global parameter PONGO_RACENTRE is used. If
PONGO_RACENTRE is not defined, the default value "0" is used.]
-
DECCENTRE = _CHAR (Read and Write)
-
The centre of the projection in declination (i.e. the angle
must be specified as dd:mm:ss.sss). This parameter is only
required for PROJECTION values other than "NONE".
[The value of the global parameter PONGO_DECCENTRE is used. If
PONGO_DECCENTRE is not defined, the default value "0" is used.]
-
ERSCALE = _REAL (Read)
-
The scale factor to be applied to the EXCOL and EYCOL data when
determining the limits of the world co-ordinates.
[The value of the global parameter PONGO_ERSCALE is used. If
PONGO_ERSCALE is not defined, the default value 1.0 is used.]
