CCG_FLX1x

Combines data lines using the integrated value

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.
