Etymology

This class contains the enums for the MeasurementSet FEED table

Synopsis

This class does nothing. It is merely a container for the enumerations used by the MSFeed class. These enumerations define the standard columns, keywords.

Example

See the documentation for MeasurementSet for examples on the use of these enumerations.

enum casacore::MSFeedEnums::PredefinedColumns

The FEED table colums with predefined meaning.

Enumerator
UNDEFINED_COLUMN	"True" columns are defined. TYPE - UNIT - MEASURE
ANTENNA_ID	Antenna Id. Int.
BEAM_ID	Index in BEAM model table. This is a specialized model e.g. NRAO_VLA_BEAM would have parameters for polynomial. Int.
BEAM_OFFSET	Beam position offset (on sky but in antenna reference frame). Double(2,NUM_RECEPTORS) - rad - DIRECTION
FEED_ID	Feed id Int.
INTERVAL	Interval for which this set of parameters is accurate Double - s.
NUM_RECEPTORS	Number of receptors on this feed (probably 1 or 2) Int.
POL_RESPONSE	D-matrix i.e. leakage between two receptors i.e. only makes sense if NUM_RECEPTORS>1. Dimensionless coupling numbers. Complex(NUM_RECEPTORS,NUM_RECEPTORS)
POLARIZATION_TYPE	Type of polarization to which a given RECEPTOR responds. Probably R, L or X, Y. String(NUM_RECEPTORS)
POSITION	Position of feed relative to feed reference position for this antenna Double(3) - m - POSITION.
RECEPTOR_ANGLE	The reference angle for polarization. Converts into Parallactic angle in the Sky domain. Double(2) - rad
SPECTRAL_WINDOW_ID	Spectral Window id Int.
TIME	Midpoint of time for which this set of parameters is accurate Double - s - EPOCH.
NUMBER_REQUIRED_COLUMNS	Number of required columns.
FOCUS_LENGTH	Focus length Double - m.
PHASED_FEED_ID	Phased feed id to index into PHASED_FEED table Int.
NUMBER_PREDEFINED_COLUMNS	Not a column, but just a final enum specifying the number of enums.

enum casacore::MSFeedEnums::PredefinedKeywords

Keywords with a predefined meaning.

Enumerator
UNDEFINED_KEYWORD	"True" keywords are defined.
NUMBER_PREDEFINED_KEYWORDS	Not a keyword, but just a final enum specifying the number of enums.
