Function Documentation

ObitSkyModelVM* newObitSkyModelVM (  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 ObitSkyModelVMChose (  ObitSkyModel *  in, ObitUV *  uvdata )

Private: Chose model type. Parameters: in  Pointer to theObitSkyModel . uvdata  UV data set

void ObitSkyModelVMClassInit (  void   )

Public: Class initializer.

ObitSkyModel* ObitSkyModelVMCopy (  ObitSkyModel *  inn, ObitSkyModel *  outt, ObitErr *  err )

Public: Copy (deep) constructor. Since this is a virtual class it only calls parent class. Parameters: inn  The object to copy outt  An existing object pointer for output or NULL if none exists. err  Obit error stack object. Returns: pointer to the new object.

ObitSkyModelVM* ObitSkyModelVMCreate (  gchar *  name, ObitImageMosaic *  mosaic )

Public: Create/initialize ObitSkyModelVM structures. Parameters: name  An optional name for the object. mosaic  ObitImageMosaic giving one or more images/CC tables Returns: the new object.

void ObitSkyModelVMFTDFT (  ObitSkyModelVM *  in, gint  field, ObitUV *  uvdata, ObitErr *  err )

Private: FT by DFT, may be overridden in derived class. Version for time/spatial dependent effects. If doDivide member is true then FT of model is divided into the data, If doReplace member is true then FT of model replaces the data, else, it is subtracted. If doFlip member is true the Fourier transform is multiplied by sqrt(-1) (for Stokes RL and LR) After the AIPSish QXXPTS, QPTDIV and friends This function may be overridden in a derived class and should always be called by its function pointer. Parameters: in  SkyModelVM with model components loaded (ObitSkyModelLoad) field  Field number being processed (-1 => all) uvdata  UV data set to model and subtract from current buffer err  Obit error stack object. Returns: return code, OBIT_IO_OK=> OK

gconstpointer ObitSkyModelVMGetClass (  void   )

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

void ObitSkyModelVMGetInput (  ObitSkyModel *  inn, ObitErr *  err )

Public: Get Inputs. Parameters: inn  Pointer to the ObitSkyModelVM . err  Obit error stack object.

void ObitSkyModelVMInitMod (  ObitSkyModel *  inn, ObitUV *  uvdata, ObitErr *  err )

Public: initialize ObitSkyModelVM structures. Recurses through inheritence heirarchy Parameters: inn  SkyModel to initialize uvdata  uv data being modeled. err  Obit error stack object. Returns: the new object.

void ObitSkyModelVMInitModel (  ObitSkyModel *  inn, ObitErr *  err )

Public: initialize model for pass through data. Parameters: inn  SkyModel to initialize err  Obit error stack object.

gboolean ObitSkyModelVMLoadComps (  ObitSkyModel *  inn, gint  n, ObitUV *  uvdata, ObitErr *  err )

Private: Load Components<. Multiplies by factor member. This function may be overridden in a derived class and should always be called by its function pointer. Adapted from the AIPSish QNOT:IONDFT Parameters: inn  SkyModel n  Image number on mosaic, if -1 load all images uvdata  UV data set to model err  Obit error stack object. Output is in member comps, the entries are Field (0-rel) CC DeltaX CC DeltaY Amplitude (Jy) -2*pi*x (radians) -2*pi*y (radians) -2*pi*z (radians) Other model parameters depending on model type Returns: TRUE iff this image produced a valid model (i.e. had some CCs).

gboolean ObitSkyModelVMLoadPoint (  ObitSkyModel *  inn, ObitUV *  uvdata, ObitErr *  err )

Private: Load point model. Multiplies by factor member. This function may be overridden in a derived class and should always be called by its function pointer. Adapted from the AIPSish QNOT:VISDFT Output is in member comps with a single row, the entries are Field (0) CC DeltaX CC DeltaY Amplitude (Jy) -2*pi*x (radians) -2*pi*y (radians) -2*pi*z (radians) Parameters: inn  SkyModel uvdata  UV data set to model err  Obit error stack object. Returns: TRUE iff this image produced a valid model (i.e. had some CCs).

void ObitSkyModelVMShutDownMod (  ObitSkyModel *  inn, ObitUV *  uvdata, ObitErr *  err )

Public: shutdown ObitSkyModel processes. Parameters: inn  SkyModel to initialize uvdata  uv data being modeled. err  Obit error stack object.

void ObitSkyModelVMUpdateModel (  ObitSkyModelVM *  in, gfloat  time, gint  suba, ObitUV *  uvdata, ObitErr *  err )

Public: Routine to update model. Parameters: in  SkyModelVM time  current time (d) suba  0-rel subarray number uvdata  uv data being modeled. err  Obit error stack object.
