Classes
- MSSpectralWindowEnums -- Enums for the MeasurementSet SPECTRAL_WINDOW table (full description)
Types
- UNDEFINED_COLUMN = 0
-
"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 = TOTAL_BANDWIDTH,
-
Not a column, but just an enum specifying the number of required columns.
- ASSOC_NATURE
-
Nature of association with other spectral window id
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 = RECEIVER_ID
-
Not a column, but just a final enum specifying the number of enums.
- UNDEFINED_KEYWORD = 0
-
"True" keywords are defined.
- NUMBER_PREDEFINED_KEYWORDS = 0
-
Not a keyword, but just a final enum specifying the number of enums.
Interface
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.
To Do
All the todo items which may be related to this class are
grouped with the todo items for MeasurementSet
Member Description
The SpectralWindow table colums with predefined meaning.
The SPECTRAL_WINDOW_ID is the row number in the table.
