Detailed Description

ObitUVGSolve Class for uv data self calibration.

This class is derived from the Obit class.

Routines determine calibration for an ObitUV and write an SN table. Control parameters are on the info member.

Creators and Destructors

An ObitUVGSolve will usually be created using ObitUVGSolveCreate which allows specifying a name for the object as well as other information.

A copy of a pointer to an ObitUVGSolve should always be made using the ObitUVGSolveRef function which updates the reference count in the object. Then whenever freeing an ObitUVGSolve or changing a pointer, the function ObitUVGSolveUnref will decrement the reference count and destroy the object when the reference count hits 0. There is no explicit destructor.

Define Documentation

#define ObitUVGSolveIsA (  in   )     ObitIsA (in, ObitUVGSolveGetClass())
 

Macro to determine if an object is the member of this or a derived class.

Returns TRUE if a member, else FALSE in = object to reference

#define ObitUVGSolveRef (  in   )     ObitRef (in)
 

Macro to reference (update reference count) an ObitUVGSolve.

returns a ObitUVGSolve*. in = object to reference

#define ObitUVGSolveUnref (  in   )     ObitUnref (in)
 

Macro to unreference (and possibly destroy) an ObitUVGSolve returns a ObitUVGSolve*.

in = object to unreference

Typedef Documentation

typedef ObitUVGSolve*(* ObitUVGSolveCreateFP)(gchar *name)
 

Typedef for definition of class pointer structure.

Function Documentation

ObitUVGSolve* newObitUVGSolve (  gchar *  name  ) 
 

Public: Default Constructor.

Initializes class if needed on first call.

Parameters:
