### DLIMITS

Set the world coordinate limits using the data range

#### Description:

The ranges of the data given in the XCOL and XCOL data areas are used to set the world coordinate limits for plotting. A small border is also added to the data limits when calculating the world coordinate limits.

This command is a synonym for WORLD DATA.

dlimits

#### Parameters:

##### 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.]
