Etymology

This class contains the enums for the MeasurementSet SPECTRAL_WINDOW 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 and keywords.

Example

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

enum casa::MSSpectralWindowEnums::PredefinedColumns

The SpectralWindow table colums with predefined meaning.

The SPECTRAL_WINDOW_ID is the row number in the table.

Enumerator:

UNDEFINED_COLUMN	"True" columns are defined. TYPE - UNIT - MEASURE
CHAN_FREQ	Center frequencies for each channel in the data matrix. Can therefore be non-linear to allow for e.g. AOS Double(NUM_CHAN) - Hz - FREQUENCY
CHAN_WIDTH	The channel width for each channel Double(NUM_CHAN) - Hz.
EFFECTIVE_BW	The effective noise bandwidth of each channel Double(NUM_CHAN) - Hz.
FLAG_ROW	Row flag Bool.
FREQ_GROUP	The frequency group Int.
FREQ_GROUP_NAME	The frequency group name String.
IF_CONV_CHAIN	The IF conversion chain (to distinguish the separate electronic paths for simultaneous observations at multiple frequencies). E.g., VLA A-C and B-D should always be numbered 0 and 1 resp. Int
MEAS_FREQ_REF	The frequency measure reference Int.
NAME	Spectral window name String.
NET_SIDEBAND	Net sideband for this spectral window (+/- 1) Int.
NUM_CHAN	Number of spectral channels Int.
REF_FREQUENCY	The reference frequency (as specified on-line). Double - Hz - FREQUENCY
RESOLUTION	The effective spectral resolution of each channel The Vector nature allows for variable-width channels. Double(NUM_CHAN) - Hz
TOTAL_BANDWIDTH	The total bandwidth (as specified on-line). Double - Hz
NUMBER_REQUIRED_COLUMNS	Not a column, but just an enum specifying the number of required columns.
ASSOC_NATURE	Nature of association with other spectral window id String(*).
ASSOC_SPW_ID	Associated spectral window id's, e.g. averaged spectra Int(*)
BBC_NO	Baseband converter number Int.
BBC_SIDEBAND	Baseband converter sideband Int.
DOPPLER_ID	Doppler id, points to DOPPLER table Int.
RECEIVER_ID	Receiver id, identifies receiver used for this spectral window. May point to optional RECEIVER table Int
NUMBER_PREDEFINED_COLUMNS	Not a column, but just a final enum specifying the number of enums.
