MSAntennaColumns.h

This class provides read-only access to the columns in the MSAntenna Table. It does the declaration of all the Scalar and ArrayColumns with the correct types, so the application programmer doesn't have to worry about getting those right. There is an access function for every predefined column. Access to non-predefined columns will still have to be done with explicit declarations. See ROMSColumns for an example.

Motivation

See MSColumns for the motivation.

Member Description

ROMSAntennaColumns(const MSAntenna& msAntenna)

Create a columns object that accesses the data in the specified Table

~ROMSAntennaColumns()

The destructor does nothing special

const ROScalarColumn<Double>& dishDiameter() const
const ROScalarQuantColumn<Double>& dishDiameterQuant() const
const ROScalarColumn<Bool>& flagRow() const
const ROScalarColumn<String>& mount() const
const ROScalarColumn<String>& name() const
const ROArrayColumn<Double>& offset() const
const ROArrayQuantColumn<Double>& offsetQuant() const
const ROScalarMeasColumn<MPosition>& offsetMeas() const
const ROArrayColumn<Double>& position() const
const ROArrayQuantColumn<Double>& positionQuant() const
const ROScalarMeasColumn<MPosition>& positionMeas() const
const ROScalarColumn<String>& station() const
const ROScalarColumn<String>& type() const

Access to columns

const ROArrayColumn<Double>& meanOrbit() const
const ROScalarColumn<Int>& orbitId() const
const ROScalarColumn<Int>& phasedArrayId() const

Access to optional columns

uInt nrow() const

Convenience function that returns the number of rows in any of the columns

Int matchAntenna(const MPosition& antennaPos, const Quantum<Double>& tolerance, Int tryRow=-1)

returns the last row that contains an antenna at the specified position, to within the specified tolerance. The reference frame of the supplied position must be the same as the one for the POSITION columns. If not an AipsError is thrown as such an argument will never match any row of the Table. The tolerance is the maximum allowed distance between the two positions and the supplied Quantum must have dimensions of length. This is checked when compiled in debug mode and an AipsError exception is thrown if the dimensions are wrong. Returns -1 if no match could be found. Flaged rows can never match. If tryRow is non-negative, then that row is tested to see if it matches before any others are tested. Setting tryRow to a positive value greater than the table length will throw an exception (AipsError), when compiled in debug mode.

Int matchAntenna(const String& antName, const MPosition& antennaPos, const Quantum<Double>& tolerance, Int tryRow=-1)

Same as the previous function except that the antenna name must also match.
