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.

enum casa::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.
