Function Documentation

ObitImageFit* newObitImageFit (  gchar *  name  )

Public: Default Constructor. Initializes class if needed on first call. Parameters: name  An optional name for the object. Returns: the new object.

void ObitImageFitClassInit (  void   )

Public: Class initializer.

void ObitImageFitClear (  gpointer  inn  )

Private: Deallocate members. Does (recursive) deallocation of parent class members. Parameters: inn  Pointer to the object to deallocate. Actually it should be an ObitImageFit* cast to an Obit*.

void ObitImageFitClone (  ObitImageFit *  in, ObitImageFit *  out, ObitErr *  err )

Public: Copy structure. Parameters: in  The object to copy out  An existing object pointer for output, must be defined. err  Obit error stack object.

ObitImageFit* ObitImageFitCopy (  ObitImageFit *  in, ObitImageFit *  out, ObitErr *  err )

Public: Copy (deep) constructor. Parameters: in  The object to copy out  An existing object pointer for output or NULL if none exists. err  Obit error stack object. Returns: pointer to the new object.

ObitImageFit* ObitImageFitCreate (  gchar *  name  )

Public: Create/initialize ObitImageFit structures. Parameters: name  An optional name for the object. Returns: the new object.

gint ObitImageFitFit (  ObitImageFit *  in, ObitImage *  image, ObitFitRegion *  reg, ObitErr *  err )

Public: Fit an ObitFitRegion. Parameters: in  Fitter to use, control info in info: "MaxIter" OBIT_int (1,1,1) Maximum number of iterations defaults to 10 per fitted parameter "prtLv" OBIT_int (1,1,1) Message level, 0=>none [def 0] "PosGuard" OBIT_double (1,1,1) Distance from edge to allow center [def no bound] "FluxLow" OBIT_double (1,1,1) Lower bounds on Flux density [no bound] "GMajUp" OBIT_double (1,1,1) Major axis upper bound [no bound] "GMajLow" OBIT_double (1,1,1) Major axis lower bound [no bound] "GMinUp" OBIT_double (1,1,1) Minor axis upper bound [no bound] "GMinLow" OBIT_double (1,1,1) Minor axis lower bound [no bound] image  Image to fit, should have pixel array attached and opened as described in reg (BLC, TRC). reg  Region in image to fit, on input the initial guess on output, the fitted result err  Obit error/message stack. Returns: a completion code: 0=> converged, 1=> max. iterations.

gconstpointer ObitImageFitGetClass (  void   )

Public: ClassInfo pointer. Returns: pointer to the class structure.

void ObitImageFitInit (  gpointer  inn  )

Private: Initialize newly instantiated object. Parent classes portions are (recursively) initialized first Parameters: inn  Pointer to the object to initialize.
