### LIMITS

Set the world coordinate limits

#### Description:

The world coordinate limits are set from the parameters given on the command line.

This command is a synonym for WORLD GIVEN.

#### Usage:

limits [xmin] [xmax] [ymin] [ymax]

#### Parameters:

##### XMIN = _REAL (Read and Write)
The world coordinate of the left-hand edge of the plot.

[The value of the global parameter PONGO_XMIN is used.]

##### XMAX = _REAL (Read and Write)
The world coordinate of the right-hand edge of the plot.

[The value of the global parameter PONGO_XMAX is used.]

##### YMIN = _REAL (Read and Write)
The world coordinate of the lower edge of the plot.

[The value of the global parameter PONGO_YMIN is used.]

##### YMAX = _REAL (Read and Write)
The world coordinate of the upper edge of the plot.

[The value of the global parameter PONGO_YMAX is used.]

##### 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.]
