Description:
This routine accepts an array
consisting a series of (vectorised) lines of data. The data values in the lines are then collapsed to
the fraction of good (or bad) values in each line. The output values are returned in the
array RESULT.
Invocation
CALL CCG_FRC3x( IMETH, NPIX, NLINES, STACK, RESULT,
NCON, NBAD, STATUS )
Arguments
IMETH = INTEGER (Given)
37 - Return the fraction
of good values in each line. 38 - Return the fraction of bad values in each line.
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.
RESULT( NPIX ) = ? (Returned)
The output line of data.
NCON( NLINES ) = DOUBLE PRECISION (Returned)
The
actual number of contributing pixels from each input line to the output line. Each value in
this array is set to NPIX.
NBAD = INTEGER (Returned)
The number of bad values in
the output array created while forming the statistics. This is always returned as zero by
this routine.
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, R, I, W, UW, B or
UB as appropriate. The STACK and RESULT arguments supplied to the routine must have the data
type specified.
