CCG_IWC3x

Combines data lines using the intensity-weighted co-ordinate

Description:

This routine accepts an array consisting of a series of (vectorised) lines of data and their co-ordinates. For each pixel the subroutine forms a weighted mean co-ordinate along a line of data. The weights are the data values. The output weighted co-ordinates are returned in the array RESULT.

Invocation

CALL CCG_IWC3x( NPIX, NLINES, STACK, COORDS, MINPIX, RESULT, NCON, STATUS )

Arguments

NPIX = INTEGER (Given)
The number of pixels in a line of data.
NLINES = INTEGER (Given)
The number of lines of data in the stack.
STACK( NPIX, NLINES ) = ? (Given)
The array of lines which are to be combined into a single line.
COORDS( NPIX, NLINES ) = ? (Given)
The world co-ordinates.
MINPIX = INTEGER (Given)
The minimum number of pixels required to contribute to an output pixel.
RESULT( NPIX ) = ? (Returned)
The output line of data.
NCON( NLINES ) = DOUBLE PRECISION (Returned)
The actual number of contributing pixels from each input line to the output line.
NBAD = INTEGER (Returned)
The number of bad values in the output array created while forming the statistics. It excludes those bad values whose corresponding values along the collapse axis are all bad.
STATUS = INTEGER (Given and Returned)
The global status.
