Detailed Description

The FeedTable class is an Alma table.

Role: Contains characteristics of the feeds.

Generated from model's revision "-1", branch ""

Attributes of Feed
Name	Type	Expected shape	Comment
Key
antennaId	Tag		refers to a unique row in AntennaTable.
spectralWindowId	Tag		refers to a unique row in SpectralWindowTable.
timeInterval	ArrayTimeInterval		the time interval of validity of the content of the row.
feedId	int		identifies a collection of rows in the table.
Value (Mandatory)
numReceptor (numReceptor)	int		the number of receptors.
beamOffset	std::vector<std::vector<double > >	numReceptor, 2	the offsets of the beam (one pair per receptor).
focusReference	std::vector<std::vector<Length > >	numReceptor, 3	the references for the focus position (one triple per receptor).
polarizationTypes	std::vector<PolarizationTypeMod::PolarizationType >	numReceptor	identifies the polarization types (one value per receptor).
polResponse	std::vector<std::vector<Complex > >	numReceptor, numReceptor	the polarization response (one value per pair of receptors).
receptorAngle	std::vector<Angle >	numReceptor	the receptors angles (one value per receptor).
receiverId	std::vector<int>	numReceptor	refers to one or more collections of rows in ReceiverTable.
Value (Optional)
feedNum	int		the feed number to be used for multi-feed receivers.
illumOffset	std::vector<Length >	2	the illumination offset.
position	std::vector<Length >	3	the position of the feed.
skyCoupling	float		the sky coupling is the coupling efficiency to the sky of the WVR radiometer's. Note that in general one expects to see whether no sky coupling efficiency recorded or only one of the two forms scalar (skyCoupling) or array (skyCouplingSpectrum, numChan).
numChan(numChan)	int		the size of skyCouplingSpectrum. This attribute must be present when the (array) attribute skyCouplingSpectrum is present since it defines its number of elements. The value of this attribute must be equal to the value of numChan in the row of the SpectralWindow table refered to by spectralWindowId.
skyCouplingSpectrum	std::vector<float >	numChan	the sky coupling is the coupling efficiency to the sky of the WVR radiometer's. This column differs from the skyCoupling column because it contains one value for each of the individual channels of that spectralWindow. See the documentation of numChan for the size and the presence of this attribute. Note that in general one expects to see whether no sky coupling efficiency recorded or only one of the two forms scalar (skyCoupling) or array (skyCouplingSpectrum, numChan).

Constructor & Destructor Documentation

virtual asdm::FeedTable::~FeedTable ( )
