CCG_AD1x

Combines data lines using absolute deviations from an unweighted mean

Description:

This routine accepts an array consisting of a series of (vectorised) lines of data. The data values in the lines are then combined to form an unweighted mean, and then the absolute mean deviation from the mean. The output means are returned in the array RESULT. The output variances are standard-error values and are returned in RESVAR.

Invocation

CALL CCG_AD1x( NPIX, NLINES, STACK, MINPIX, RESULT, RESVAR, 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.
RESVAR( NPIX ) = ? (Returned)
The output variances.
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 RESULT 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.
