Description:
This routine
accepts an array consisting a series of (vectorised) lines of data. All values outside of the range VMIN
to VMAX are rejected before a estimate of the (weighted) mean is made. The output mean values are
returned in the array RESULT. The variances are propagation through the combination process and
returned in the RESVAR array.
Invocation
CALL CCG_TC1x( VMIN, VMAX, NPIX, NLINES, STACK,
VARS, MINPIX, COVEC, NMAT, RESULT, RESVAR, WRK1, WRK2, POINT, USED, NCON, NBAD,
STATUS )
Arguments
VMIN = ? (Given)
Minimum allowed value.
VMAX = ? (Given)
Maximum allowed value.
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.
VARS(
NPIX, NLINES ) = ? (Given)
The data variances.
MINPIX = INTEGER (Given)
The
minimum number of pixels required to contribute to an output pixel.
NMAT = INTEGER
(Given)
Size of the first dimension of COVEC.
COVEC( NMAT, NLINES ) = DOUBLE
PRECISION (Given)
The packed variance-covariance matrix of the order statistics from a normal
distribution of sizes up to NLINES, produced by CCD1_ORVAR.
RESULT( NPIX ) = ?
(Returned)
The output line of data.
RESVAR( NPIX ) = ? (Returned)
The output variance.
WRK1( NLINES ) = ? (Returned)
Workspace for calculations.
WRK2( NLINES ) = ?
(Returned)
Workspace for calculations.
POINT( NLINES ) = INTEGER (Returned)
Workspace to hold pointers to the original positions of the data before extraction and conversion
in to the WRK1 array.
USED( NLINES ) = LOGICAL (Returned)
Workspace used to
indicate which values have been used in estimating a resultant value.
NCON( NLINES ) =
DOUBLE PRECISION (Returned)
The actual number of contributing pixels.
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 VMIN, VMAX, STACK, VARS, RESULT, RESVAR, WRK1, and WRK2 arguments
supplied to the routine must have the data type specified.
