Etymology

This class contains the enum defininitions for the main MeasurementSet table.

Synopsis

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

Example

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

◆ PredefinedColumns

enum casacore::MSMainEnums::PredefinedColumns

The Main table colums with predefined meaning.

Enumerator
UNDEFINED_COLUMN	"True" columns are defined. TYPE - UNIT - MEASURE
ANTENNA1	ID of first antenna in antenna-pair. This is a key into the ANTENNA table. Ranges from 0 to NUM_ANT-1. Int
ANTENNA2	ID of second antenna in antenna-pair. For SD ANTENNA1==ANTENNA2 Int
ARRAY_ID	ARRAY id. Int.
DATA_DESC_ID	Data description id Int.
EXPOSURE	Effective integration time (i.e. <=INTERVAL) Double - s.
FEED1	Feed id on ANTENNA1. Int.
FEED2	Feed id on ANTENNA2. Int.
FIELD_ID	Unique id for this pointing (or drift scan) Int.
FLAG	The data flags, array of bools with same shape as data. Data is flagged bad if FLAG is True. Bool(Nc, Nf)
FLAG_CATEGORY	Flag category, allows for multiple categories of flagging, which can selectively be reset. The cumulative effect is reflected in FLAG. This column should have an attached keyword CATEGORY which is a String (Ncat) of categories (e.g, ONLINE, FLAG_CMD, INTERACTIVE) Bool (Nc, Nf, Ncat)
FLAG_ROW	Flag all data in this row if True. Bool
INTERVAL	The extent of this sample, sampling interval. Double - s.
OBSERVATION_ID	Index into OBSERVATION table. Int.
PROCESSOR_ID	Processor Id, points to PROCESSOR table with information on the correlator or backend setup. Int
SCAN_NUMBER	Scan number. Int.
SIGMA	Estimated rms noise for channel with unity bandpass response. Float(Nc) - Same units as the DATA column.
STATE_ID	State Id, points to STATE table with info on current observing mode, calibration and reference signals etc. (Mainly single dish) Int
TIME	Modified Julian Day number (JD-2400000.5) for midpoint of integration. For high precision timing, add the value from TIME_EXTRA_PREC. Double - s - EPOCH.
TIME_CENTROID	Modified Julian Day number (JD-2400000.5) for centroid of integration. Double - s - EPOCH.
UVW	UVW coordinates. Double(3) - m - UVW.
WEIGHT	Weight of spectrum. This is the weight assigned by the correlator and does NOT get overwritten by e.g. imaging tasks that do weighting. Float(Nc).
NUMBER_REQUIRED_COLUMNS	Not a column, but just an enum specifying the number of required columns.
ANTENNA3	Antenna3 - for triple correlations products. Int
BASELINE_REF	Reference antenna for this baseline, True for ANTENNA1 Bool.
CORRECTED_DATA	The Corrected complex visibility data (optional). Complex(Nc, Nf)
DATA	Complex visibility matrix. The UNITS are unspecified to allow for the calibrated data to show up as a DATA column as well but in a calibrated MS. Complex(Nc, Nf)
FEED3	Feed id on ANTENNA3 Int.
FLOAT_DATA	Floating point data column. For simple single dish work this can be used instead of the complex DATA column. Float(Nc, Nf)
IMAGING_WEIGHT	The imaging weights (optional). Float(Nf)
LAG_DATA	Complex correlation function or lag spectrum for each correlation product Complex(Nc, Nl)
MODEL_DATA	The model visibility data (optional). Complex(Nc,Nf)
PHASE_ID	Switching phase Id Int.
PULSAR_BIN	For a pulsar the correlations are assumed to be measured for a limited number of pulse phase bins. This is the particular bin for which this data was measured. (optional) Int.
PULSAR_GATE_ID	Unique id for this pulsar gate. Index into PULSAR_GATE table. (optional) Int.
SIGMA_SPECTRUM	Estimated rms noise for each data point. To be used instead of SIGMA if present. Float(Nc,Nf) - Same units as the DATA column.
TIME_EXTRA_PREC	Additional precision for TIME if required. Add this to TIME to obtain the exact EPOCH. Double - s.
UVW2	UVW for second pair of triple correlation product. Double(3) - m
VIDEO_POINT	Zero frequency point - needed for transform back to lag domain Complex(Nc)
WEIGHT_SPECTRUM	Weight for each channel. To be used instead of WEIGHT if present. Float(Nf).
CORRECTED_WEIGHT_SPECTRUM	Corrected Weight for each channel. If present can be used with corrected_data Float(Nf).
NUMBER_PREDEFINED_COLUMNS	Not a column, but just a final enum specifying the number of enums.
