Here are the classes, structs, unions and interfaces with brief descriptions:

[detail level 123]

▼Nast	AST wrapper classes and functions
CChannel	Channel provides input/output of AST objects
CChebyDomain	The domain over which a Chebyshev polynomial is defined; returned by ChebyMap.getDomain
CChebyMap	A ChebyMap is a form of Mapping which performs a Chebyshev polynomial transformation
CCmpFrame	A CmpFrame is a compound Frame which allows two component Frames (of any class) to be merged together to form a more complex Frame
CCmpMap	Abstract base class for SeriesMap and ParallelMap
CDirectionPoint	Struct returned by Frame::offset2 containing a direction and a point
CFileStream	File-based source or sink (not both) for channels
CFitsChan	A specialized form of Channel which reads and writes FITS header cards
CFitsTable
CFoundValue	A value and associated validity flag
CFrame	Frame is used to represent a coordinate system
CFrameDict	A FrameSet whose frames can be referenced by domain name
CFrameMapping	Struct returned by Frame::pickAxes containing a frame and a mapping
CFrameSet	A FrameSet consists of a set of one or more Frames (which describe coordinate systems), connected together by Mappings (which describe how the coordinate systems are inter-related)
CKeyMap	KeyMap is used to store a set of values with associated keys which identify the values
CLutMap	LutMap is a specialised form of Mapping which transforms 1-dimensional coordinates by using linear interpolation in a lookup table
CMapBox	Object to compute the bounding box which just encloses another box after it has been transformed by a mapping
CMapping	An abstract base class for objects which transform one set of coordinates to another
CMapSplit	A Mapping split off as a subset of another Mapping
CMathMap	A MathMap is a Mapping which allows you to specify a set of forward and/or inverse transformation functions using arithmetic operations and mathematical functions similar to those available in C
CMatrixMap	MatrixMap is a form of Mapping which performs a general linear transformation
CNormMap	A Mapping which normalises coordinate values using the norm method of the supplied Frame
CNReadValue	Struct returned by Frame::unformat containing the number of characters read and corresponding value
CObject	Abstract base class for all AST objects
CParallelMap	A parallel compound mapping where the first Mapping is used to transform the lower numbered coordinates of each point and the second Mapping is used to transform the remaining coordinates
CPcdMap	A PcdMap is a non-linear Mapping which transforms 2-dimensional positions to correct for the radial distortion introduced by some cameras and telescopes
CPermMap	A Mapping which permutes the order of coordinates, and possibly also changes the number of coordinates, between its input and output
CPolyMap	PolyMap is a Mapping which performs a general polynomial transformation
CQuadApprox	A quadratic approximation to a 2D Mapping
CRateMap	RateMap is a Mapping which represents a single element of the Jacobian matrix of another Mapping
CResolvedPoint	Struct returned by Frame::resolve containing a point and the resolved vector components
CSeriesMap	A series compound mapping where the first Mapping is used to transform the coordinates of each point and the second Mapping is then applied to the result
CShiftMap	ShiftMap is a linear Mapping which shifts each axis by a specified constant value
CSkyFrame	SkyFrame is a specialised form of Frame which describes celestial longitude/latitude coordinate systems
CSlaMap	SlaMap is a specialised form of Mapping which can be used to represent a sequence of conversions between standard celestial (longitude, latitude) coordinate systems
CSpecFrame	A specialised form of one-dimensional Frame which represents various coordinate systems used to describe positions within an electro-magnetic spectrum
CSphMap	A SphMap is a Mapping which transforms points from a 3-dimensional Cartesian coordinate system into a 2-dimensional spherical coordinate system (longitude and latitude on a unit sphere centred at the origin)
CSplineMap	SplineMap is a Mapping which performs a 2-in, 2-out Mapping defined by a pair of two- dimensional B-spline surfaces
CStream	A stream for ast::Channel
CStringStream	String-based source and sink for channels
CTable
CTimeFrame	A TimeFrame is a specialised form of one-dimensional Frame which represents various coordinate systems used to describe positions in time
CTimeMap	A TimeMap is a specialised form of 1-dimensional Mapping which can be used to represent a sequence of conversions between standard time coordinate systems
CTranMap	TranMap is a Mapping which combines the forward transformation of a supplied Mapping with the inverse transformation of another supplied Mapping, ignoring the un-used transformation in each Mapping (indeed the un-used transformation need not exist)
CUnitMap	A UnitMap is a unit (null) Mapping that has no effect on the coordinates supplied to it
CUnitNormMap	The forward transformation of a UnitNormMap subtracts the specified centre and then transforms the resulting vector to a unit vector and the vector norm
CWcsMap	Map from a spherical system to a cartesian system using standard FITS sky coordinate projections
CWinMap	A WinMap is a linear Mapping which transforms a rectangular window in one coordinate system into a similar window in another coordinate system by scaling and shifting each axis (the window edges being parallel to the coordinate axes)
CXmlChan	XmlChan provides input/output of AST objects
CZoomMap	A Mapping which "zooms" a set of points about the origin by multiplying all coordinate values by the same scale factor
