CCG_SD3x

Combines data lines using an unweighted standard deviation

Description:

This routine accepts an array consisting a series of (vectorised) lines of data. The data values in each lines are then combined to form an unweighted standard deviation. The output standard deviations are returned in the array RESULT.

Invocation

CALL CCG_SD3x( NPIX, NLINES, STACK, MINPIX, RESULT, NCON, NBAD, 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.
MINPIX = INTEGER (Given)
The minimum number of pixels required to contribute to an output pixel.
RESULT( NPIX ) = ? (Returned)
The output line of data. to the output line.
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.
