ObitTableVZ* ObitTableVL2VZ (  ObitTableVL *  in, ObitData *  data, ObitErr *  err )

Public: Convert a VL table to a VZ (short) table. Parameters: in  Input VL table Control parameters on info object: "minFlux" OBIT_float (1,1,1) Minimum acceptable flux density (Jy) data  Data object onto which the output VZ table it to be attached Frequency in data header assumed to be that of the VL table err  ObitErr error stack.

void ObitTableVLAppend (  ObitTableVL *  in, ObitTableVL *  out, ObitErr *  err )

Public: Append one VL table to another. Drops deselected entries (both AIPS and FITS). Parameters: in  Input VL table out  Output VL table *err  ObitErr error stack.

void ObitTableVLCal (  ObitTableVL *  in, ObitErr *  err )

Public: Apply final calibration and error analysis. Parameters: in  Input VL table *err  ObitErr error stack.

void ObitTableVLIndex (  ObitTableVL *  in, ObitErr *  err )

Public: Index a VL table. Parameters: in  Input VL table *err  ObitErr error stack.

void ObitTableVLMerge (  ObitTableVL *  in, ObitErr *  err )

Public: Merge overlapping components. The resultant position is the weighted average and the flux is the sum. This should be run on a table with all entries derived from the same image. Adopted from the AIPSish task VLMRG Parameters: in  Input VL table Control parameters on info object: "Radius" OBIT_float (1,1,1) The radius in pixels within which to sum components. [def 3.01] "Cutoff" OBIT_float (1,1,1) The minimum acceptable fraction of summed flux. [def 0.05] "begRow" OBIT_int (1,1,1) First row to include [def 1] "endRow" OBIT_int (1,1,1) last row to include [def or 0 = all] *err  ObitErr error stack.

void ObitTableVLPrint (  ObitTableVL *  in, ObitImage *  image, FILE *  prtFile, ObitErr *  err )

Public: Write human readable version of an VL table to a FILE. Parameters: in  VL table to print prtFile  Where to write *err  ObitErr error stack.

void ObitTableVLPurge (  ObitTableVL *  in, gchar *  field, ObitErr *  err )

Public: Remove entries from a given field. Parameters: in  Input VL table field  Field name to purge (8 char, blank filled) *err  ObitErr error stack.

void ObitTableVLRedun (  ObitTableVL *  in, ObitTableVL *  out, ObitErr *  err )

Public: Remove redundant entries. If a positional match (maxDist) is found then the one closest to the center of its image (centerPix) is chosen. The other entry is flagged in the input table. When the search over the RA range from the original source is finished the final accepted entry is written to the output table. Adopted from the AIPSish task VREDN Parameters: in  Input VL table, will be sorted if needed Control parameters on in->info object: "centerPix" OBIT_int (2,1,1) Center pixel in images [def 512,512] "maxDist" OBIT_float (1,1,1) How far (") to search for matches [def 15"] "begRow" OBIT_int (1,1,1) First row to include [def 1] "endRow" OBIT_int (1,1,1) last row to include [def or 0 = all] out  Output VL table *err  ObitErr error stack.

void ObitTableVLSelect (  ObitTableVL *  in, ObitTableVL *  out, ObitErr *  err )

Public: Select significant components. For any non zero entry in Steps, if the entry has a peak weaker than fraction of the total within radius then it is not copied to the output. This should be run on a table with all entries derived from the same image. Adopted from the AIPSish task VLSEL Parameters: in  Input VL table Control parameters on info object: "Steps" OBIT_float (2,?,1) Pairs of values giving (radius(cells), fraction), empty entries zero filled Example: {{2.0,0.05}, {3.0,0.02}, {4.0,0.01}} "BLC" OBIT_int (2,1,1) Lowest x,y pixel number selected [def 1,1] "TRC" OBIT_int (2,1,1) Highest pixel number selected [def or 0 = all] "begRow" OBIT_int (1,1,1) First row to include [def 1] "endRow" OBIT_int (1,1,1) last row to include [def or 0 = all] out  Output VL table *err  ObitErr error stack.

ObitTableVZ* ObitTableVZSel (  ObitTableVZ *  in, ObitData *  data, ObitErr *  err )

Public: Select entries in a VZ (short) table. Parameters: in  Input VZ table Control parameters on info object: "clip" OBIT_float scalar Minimum acceptable for clipping (Jy) (used if doClip, no default) "nearest" OBIT_float scalar Minimum nearest neighbor to be considered isolated (deg) (used if doIsol, doAver, no default) "distAvg" OBIT_float scalar Distance within to average sources (deg) (used if doAver, no default) "ignore" OBIT_float scalar Minimum acceptable flux density (Jy) (used if doAver, doIsol, no default) "crowd" OBIT_float scalar Distance (deg) for crowding test (used if doAver, default=nearest) "doClip" OBIT_boolean scalar Clipping by minPeak [def FALSE] "doIsol" OBIT_boolean scalar Select isolated entries within nearest ignore entries fainter than ignore [def FALSE] "doAver" OBIT_boolean scalar Average entries within distAvg reject outliers [def FALSE] If the brightest source within nearest is fainter than ignore then the source is passed, else: If a component is the brightest within nearest then all components within distAvg are merged. If the source has no companions within nearest it is passed. If the component has brighter companions within nearest, it is dropped. data  Data object onto which the output VZ table is to be attached *err  ObitErr error stack.
