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.

Definition at line 61 of file MSSpWindowEnums.h.

Member Enumeration Documentation

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.

Definition at line 65 of file MSSpWindowEnums.h.

Keywords with a predefined meaning.

Enumerator
UNDEFINED_KEYWORD 

"True" keywords are defined.

NUMBER_PREDEFINED_KEYWORDS 

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

Definition at line 142 of file MSSpWindowEnums.h.
