Name

ccdsub - sub/average of an image

Synopsis

ccdsub [parameter=value]

Description

ccdsub takes a subimage from an image, as described by a new set of coordinates in X, Y and/or Z (since the expression of the selected axes is arbitrary, the resulting coordinate system may be bogus).

Since cubes/images produced by this program may have dummy axes (length 1), you will need to use ccdslice(1NEMO) to get rid of them.

Parameters

The following parameters are recognized in any order if the keyword is also given:
in=
Input image file
out=
Output image file
x=
X coordinates to select. Valid numbers are 1..nx. By default all will be selected.
y=
Y coordinates to select. Valid numbers are 1..ny. By default all will be selected.

z=
Z coordinates to select. Valid numbers are 1..nz. By default all will be selected.
aver=
Coordinates to average
nxaver=
Number X to aver (size remains same)
nyaver=
Number Y to aver (size remains same)
skip=
Coordinates to skip
