CLUMPINFO

Obtain information about one or more previously identified clumps

Description:

This application returns various items of information about a single clump, or a collection of clumps, previously identified using FINDCLUMPS or EXTRACTCLUMPS.

Usage:

clumpinfo ndf clumps quiet

Parameters:

CLUMPS = LITERAL (Read)
Specifies the indices of the clumps to be included in the returned information. It can take any of the following values:
  • " ALL" or "" – All clumps.

  • " xx,yy,zz" – A list of clump indices.

  • " xx:yy" – Clump indices between xx and yy inclusively. When xx is omitted the range begins from one; when yy is omitted the range ends with the final clump index.

  • Any reasonable combination of above values separated by commas.

FLBND( ) = _DOUBLE (Write)
The lower bounds of the bounding box enclosing the selected clumps in the current WCS Frame of the input NDF. Celestial axis values are always in units of radians, but spectral axis units will be in the spectral units used by the current WCS Frame.
FUBND( ) = _DOUBLE (Write)
The upper bounds of the bounding box enclosing the selected clumps. See parameter FLBND for more details.
LBOUND( ) = _INTEGER (Write)
The lower pixel bounds of bounding box enclosing the selected clumps.
NCLUMPS = _INTEGER (Write)
The total number of clumps descrriptions stored within the supplied NDF.
NDF = NDF (Read)
The NDF defining the previously identified clumps. This should contain a CUPID extension describing all the identified clumps, in the format produced by FINDCLUMPS or EXTRACTCLUMPS.
QUIET = _LOGICAL (Read)
If TRUE, then no information is written out to the screen, although the output parameters are still assigned values. [FALSE]
UBOUND( ) = _INTEGER (Write)
The upper pixel bounds of bounding box enclosing the selected clumps.
