MAP_CENTER Character String
Specify the Map center and orientation in the same way as the arguments
of UV_MAP.
LET MAP_CENTER "ANGLE AngleValue" ! Rotation angle
LET MAP_CENTER "Ax Ay Unit" ! Center position
where Unit is any of DEGREE, MINUTE, SECOND, RADIAN or ABSOLUTE. These
two possibilities can be combined in any order:
LET MAP_CENTER "ANGLE AngleValue Ax Ay Unit"
LET MAP_CENTER "Ax Ay Unit ANGLE AngleValue"
In the latter case, the keyword ANGLE can be omitted.
For Unit ABSOLUTE, Ax Ay should be the RA and Dec in standard sexagesi-
mal notation. As usual in SIC, keywords can be abbreviated provided they
are not ambiguous.
