application copies bad pixels
from one NDF
file to another. It takes in two NDFs
(Parameters IN and REF), and creates a third (Parameter OUT) which is a copy of IN,
except that any pixel which is set bad in the DATA array of REF, is also set bad in the
DATA and VARIANCE
(if available) arrays in OUT.
By setting the INVERT Parameter
TRUE, the opposite effect can be produced (i.e. any
pixel that is not set bad in the DATA array of REF, is set bad in OUT and the others
are left unchanged).
copybad in ref out [title]
IN = NDF
NDF containing the data to be copied to OUT.
INVERT = _LOGICAL (Read)
TRUE, then the bad and good pixels within the reference NDF specified by Parameter REF
are inverted before being used (that is, good pixels are treated as bad and bad pixels
are treated as good).
OUT = NDF (Write)
The output NDF.
NDF containing the bad pixels to be copied to OUT.
The title for the output NDF. A null value will cause the
title of the NDF supplied for Parameter IN to be used instead.
NBAD = _INTEGER (Write)
The number of bad pixels copied to the output
NGOOD = _INTEGER (Write)
The number of pixels not made bad in the
copybad in=a ref=b out=c title="New image" This
creates a NDF called c, which is a copy of the NDF called a. Any bad pixels
present in the NDF called b are copied into the corresponding positions in c
(non-bad pixels in b are ignored). The title of c is
