Prerequisite

Etymology

MSSelectionKeywords is a class that defines selection keywords

Synopsis

This class is used to specify selections on a MeasurementSet. It is a purely static class that just defines a mapping from Strings to Enums, and provides these for use by classes like MSSelector and MSRange

Example

Motivation

Selection keywords are needed for several classes, this class provides them to all, avoiding duplication in each class.

Member Enumeration Documentation

enum casa::MSSelectionKeywords::Field

The fields in the MS for which selection and range operations are defined.

Some of these directly correspond to columns in the table, others are derived quantities or columns in subtables.

Enumerator:

UNDEFINED	undefined field
AMPLITUDE	the range of visibility amplitude
CORRECTED_AMPLITUDE	the range of corrected vis amplitude
MODEL_AMPLITUDE	the range of model vis amplitude
RATIO_AMPLITUDE	the amplitude of the ratio corrected data/model data
RESIDUAL_AMPLITUDE	the residual vis amplitude (corrected-model)
OBS_RESIDUAL_AMPLITUDE	the observed residual vis amplitude (observed-model)
ANTENNA1	the list of antenna1 id values
ANTENNA2	the list of antenna2 id values
ANTENNAS	the list of antenna names
ARRAY_ID	the list of array id values
AXIS_INFO	description of the data axes
CHAN_FREQ	the channel frequencies, a vector for each selected spectral window
CORR_NAMES	the list of polarizations present, this gives the String values
CORR_TYPES	the list of polarizations present, this gives the Stokes enum values
DATA	the complex data
CORRECTED_DATA	the complex corrected data
MODEL_DATA	the complex model data
RATIO_DATA	the ratio corrected data/model data
RESIDUAL_DATA	the residual data (corrected - model)
OBS_RESIDUAL_DATA	the observed residual data (observed - model)
DATA_DESC_ID	the list of dataDescription id values
FEED1	the list of feed1 id values
FEED2	the list of feed2 id values
FIELD_ID	the list of field_id values
