Description:
This routine accepts
an array consisting a series of (vectorised) lines of data. The data values in the lines are
then combined to form an unweighted mean. The output means are returned in the array
RESULT.
Invocation
CALL CCG_UM3x( 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.
Notes:
-
There is a routine for real and double-precision: replace " x" in the routine name by D or R as
appropriate. The STACK, VARS, and RESULT arguments supplied to the routine must have the data
type specified.
-
This routine performs its work in double precision.
