Prerequisite

Measure class

Etymology

From Measure and Baseline

Synopsis

MBaseline forms derived Measure class for an interferometer baseline. Baselines can be given in any of the direction types, or as ITRF, the IERS base.
Note that at the moment no correction for Earth tides (error <~ 0.05 mm/km EW baseline), plate motion (not relevant for telescopes on same plate) and relativistic effects are incorporated. B1950 has the same caveat as in MDirection.

Example

Motivation

To Do

add some Earth tide model

Member Description

enum Types

Types of known MBaselines

The order defines the order in the translation matrix FromTo in the getConvert routine. Do not change the order without changing the array. Additions should be made before N_types, and an additional row and column should be coded in FromTo, and in showType().

typedef WHATEVER_SUN_TYPEDEF(MBaseline) Types Types

Reference enum Types (included originally for gcc 2.95)

MBaseline()

In the following constructors and other functions, all MeasRef can be replaced with simple Measure::TYPE where no offsets or frames are needed in the reference.

Default constructor; generates the ITRF centre

MBaseline(const MVBaseline &dt)
MBaseline(const MVBaseline &dt, const MBaseline::Ref &rf)
MBaseline(const MVBaseline &dt, MBaseline::Types rf)
MBaseline(const Measure dt)
MBaseline(const MeasValue dt)

Create from data and reference

MBaseline(const MBaseline &)
MBaseline &operator=(const MBaseline &)

virtual ~MBaseline()

virtual const String &tellMe() const
static const String &showMe()
virtual uInt type() const
static void assure(const Measure &in)

Tell me your type

static MBaseline::Types castType(uInt tp)
static const String &showType(MBaseline::Types tp)
static const String &showType(uInt tp)

Translate reference code. The uInt version has a check for valid codes (i.e. it is a safe cast).

Thrown Exceptions

AipsError in the uInt interface if illegal code given

static Bool getType(MBaseline::Types &tp, const String &in)
Bool giveMe(MBaseline::Ref &mr, const String &in)

Translate string to reference code

virtual Bool setOffset(const Measure &in)

Set the offset in the reference (False if non-matching Measure)

virtual Bool setRefString(const String &in)

Set the reference type to the specified String. False if illegal string, reference set to DEFAULT.

virtual const String &getDefaultType() const

Get the default reference type

virtual const String const allTypes(Int &nall, Int &nextra, const uInt &typ) const
static const String const allMyTypes(Int &nall, Int &nextra, const uInt &typ)

Get a list of all known reference codes. nall returns the number in list, nextra the number of specials (like planets) that should be at end of list). typ returns the list of corresponding types.

virtual void checkTypes() const
static void checkMyTypes()

Check if all internal tables of types (both enum and String) are complete and correct. This function is called automatically if and when necessary.

Thrown Exceptions

AipsError if a (programming) error in the types.

static MBaseline::Types fromDirType(const MDirection::Types in)
static MDirection::Types toDirType(const MBaseline::Types in)

Get the correct MBaseline type from a given direction type (or v.v.)

virtual String getRefString() const

Get the reference type (for records, including codes like R_)

static uInt myType()

Get my type (as Register)

Quantum<Vector<Double> > get(const Unit &inunit) const
Quantum<Vector<Double> > getAngle() const
Quantum<Vector<Double> > getAngle(const Unit &inunit) const

Get Measure data

virtual Measure *clone() const

Make copy
