MSFeedEnums -- Enums for the MeasurementSet FEED table (full description)

class MSFeedEnums

Types

enum PredefinedColumns

UNDEFINED_COLUMN = 0

"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 = TIME,

Number of required columns

FOCUS_LENGTH

Focus length
Focus length
Double - m

PHASED_FEED_ID

Phased feed id to index into PHASED_FEED table
Int

NUMBER_PREDEFINED_COLUMNS = PHASED_FEED_ID

Not a column, but just a final enum specifying the number of enums.

enum PredefinedKeywords

UNDEFINED_KEYWORD = 0

"True" keywords are defined.

NUMBER_PREDEFINED_KEYWORDS = 0

Not a keyword, but just a final enum specifying the number of enums.
