Description:
This routine accepts
an array consisting of a series of (vectorised) lines of data. It forms the sum of the data values
multiplied by its pixel width lines are then summed, i.e a flux. The output integrated values are
returned in the array RESULT. The output variances are estimated from the VARS values
and are returned in RESVAR; this assumes no errors in the widths.
Invocation
CALL
CCG_FLX1x( NPIX, NLINES, STACK, VARS, WIDTHS, 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.
VARS( NPIX, NLINES ) = ? (Given)
The data variances.
WIDTHS( NPIX, NLINES ) = ?
(Given)
The pixel widths in world co-ordinates.
MINPIX = INTEGER (Given)
The
minimum number of pixels required to contribute to an output pixel.
RESULT( NPIX ) =
TYPE
(Returned)
The output line of data.
RESVAR( NPIX ) =
TYPE
(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.
Notes:
-
There is a routine for each numeric data type: replace "
x"
in the routine name by D or R as
appropriate. The STACK, VARS, RESULT, and RESVAR arguments supplied to the routine must have
the data type specified.
