Member Function Documentation

bool casa::DS9Coordinate::isValid

(

)

const

Returns true if this coordinate is valid, false otherwise.

If the coordinate is invalid (such as an unset unit), the method will attempt to fix it.

void casa::DS9Coordinate::set	(	double	val1,
		double	val2,
		double	val3,
		bool	minusZero = false
	)

Sets the HMS/DMS value to the given.

minusZero is used when the first value is zero, but the whole value is negative.

void casa::DS9Coordinate::set

(

double

value

)

Sets the single value to the given.

void casa::DS9Coordinate::set

(

DS9::CoordinateUnit

unit

)

Sets the coordinate unit to the given.

void casa::DS9Coordinate::set

(

DS9::CoordinateSystem

system

)

Sets the coordinate system to the given.

unsigned int casa::DS9Coordinate::size

(

)

const

Returns 1 for normal coordinates or 3 for HMS/DMS.

DS9::CoordinateSystem casa::DS9Coordinate::system

(

)

const

Returns the coordinate system.

double casa::DS9Coordinate::toDegrees

(

)

const

Returns the value in degrees.

String casa::DS9Coordinate::toPrintString

(

)

const

Returns a String version for use with DS9Region::toPrintString.

DS9::CoordinateUnit casa::DS9Coordinate::unit

(

)

const

Returns the unit.

double casa::DS9Coordinate::value

(

)

const

Returns the first value.

No conversion is used.

vector<double> casa::DS9Coordinate::values

(

)

const

Returns the value(s).

Size will be 1 for normal coordinates, 3 for HMS/DMS. No conversion is used.
