Function Documentation

void ObitTableCCUtilAppend (  ObitTableCC *  inCC, ObitTableCC *  outCC, gint  startComp, gint  endComp, ObitErr *  err )

Append CLEAN components from one table to another. Parameters: inCC  Table to copy from outCC  Table to copy to startComp  First component to select , 0=>1 endComp  Last component to select, 0=> all err  ObitErr error stack.

ObitFArray* ObitTableCCUtilCrossList (  ObitTableCC *  inCC, ObitImageDesc *  inDesc, ObitImageDesc *  outDesc, gfloat  gparm[3], glong *  ncomps, ObitErr *  err )

Public: return list of CC from one image overlapping another. Returned array has component values on the first axis and one row per overlapping component. (X cell (0-rel), Y cell (0-rel), flux). CCs on cells within 0.5 pixels of outDesc are included. Components in the same cell are combined. If the components are Gaussians, their parameters are returned in gaus. Parameters: in  Table of CCs inDesc  Descriptor for image from which components derived outDesc  Descriptor for output image grid  [out] filled in array, created, resized if necessary gparm  [out] Gaussian parameters (major, minor, PA (all deg)) if the components in in are Gaussians, else, -1. These are the values from the first CC. ncomp  [out] number of components in output list (generally less than size of FArray). err  ObitErr error stack. Returns: pointer to list of components, may be NULL on failure, MUST be Unreffed.

gboolean ObitTableCCUtilFiltCC (  ObitTableCC *  CCTab, gfloat  radius, gfloat  minFlux, ObitErr *  err )

Filter weak, isolated components. Parameters: CCTab  CC table object to filter. radius  Radius within which to consider components. (deg) minFlux  Minimum acceptable summed flux err  Error/message stack Returns: True if any components zeroed

ObitIOCode ObitTableCCUtilGrid (  ObitTableCC *  in, glong  OverSample, glong *  first, glong *  last, gboolean  noNeg, gfloat  factor, gfloat  minFlux, gfloat  maxFlux, ObitImageDesc *  desc, ObitFArray **  grid, gfloat  gparm[3], glong *  ncomp, ObitErr *  err )

Public: grid components onto a grid. The image from which the components is derived is described in desc. The output grid is padded by a factor OverSample. If the components are Gaussians, their parameters are returned in gaus. Parameters: in  Table to grid OverSample  Expansion factor for output image first  First component (1-rel) to include, 0=>1, filled in if changed last  Last component (1-rel) to include, 0=>all, filled in if changed noNeg  Ignore first negative flux component and after factor  factor to multiply timec fluxes minFlux  Minimum abs. value flux density to include (before factor) maxFlux  Maximum abs. value flux density to include (before factor) desc  Descriptor for image from which components derived grid  [out] filled in array, created, resized if necessary gparm  [out] Gaussian parameters (major, minor, PA all in deg) if the components in in are Gaussians, else, -1. ncomp  [out] number of components gridded. err  ObitErr error stack. Returns: I/O Code OBIT_IO_OK = OK.

ObitIOCode ObitTableCCUtilMerge (  ObitTableCC *  in, ObitTableCC *  out, ObitErr *  err )

Merge elements of an ObitTableCC. First sorts table, collapses, sorts to desc. flux Parameters: in  Table to sort out  Table to write output to err  ObitErr error stack. Returns: I/O Code OBIT_IO_OK = OK.

ObitFArray* ObitTableCCUtilMergeSel (  ObitTableCC *  in, gint  startComp, gint  endComp, gfloat *  parms, ObitErr *  err )

Merge elements of an ObitTableCC with selection. with selection by row number. First sorts table, collapses, sorts to desc. flux Parameters: in  Table to sort startComp  First component to select endComp  Last component to select, 0=> all parms  [out] Non-point parameters (MUST all be the same ) dimen. at least 4. parms[3] = type 0 => point, no parameters 1 = Sky Gaussian, [0:3]=maj, min, PA 2 = Convolved Gaussian, [0:3]=maj axis, min axis, PA (all deg) 3 = Uniform Sphere [0] = radius (deg) err  ObitErr error stack. Returns: FArray containing merged CC table contents; MUST be Unreffed. Flux Delta X Delta Y

ObitTableCC* ObitTableCCUtilMergeSel2Tab (  ObitImage *  image, glong  inCCver, glong *  outCCver, gint  startComp, gint  endComp, gfloat  range[2], ObitErr *  err )

Merge selected elements of an ObitTableCC to a new table. Parameters: image  input image with input CC table inCCver  input CC table outCCver  Desired output CC table on image, if 0 then new value used returned. startComp  First component to select endComp  Last component to select, 0=> all range  Max and min abs value of flux densities to accept err  ObitErr error stack.

void ObitTableCCUtilScale (  ObitTableCC *  in, gint  startComp, gint  endComp, gfloat  scale, ObitErr *  err )

Scale the flux densities of entries in a CC table. Parameters: in  Table to scale startComp  First component to select endComp  Last component to select, 0=> all scale  Factor to multiply times flux densities err  ObitErr error stack.
