* Name:
* CLUMPINFO
* Purpose:
* Obtain information about one or more previously identified clumps.
* Language:
* C
* Type of Module:
* ADAM A-task
* 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
* ADAM 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.
* Notes:
* - It is hoped to extend the range of information reported by this
* application as new requirements arise.
