ccdmerge - merge all input images into one big cube
ccdmerge
[parameter=value]
ccdmerge merges all the images in an input
file into a single large image cube.
The following parameters
are recognized in any order if the keyword is also given:
- in=
- Input image
file, Individual images can be cubes also. No default.
- out=
- Output image
cube file. No default.
It uses a conservative approach by in a single
read
to read in all input images, to make it easy to allocate the output cube.
It is therefore every memory intensive, since it needs twice the memory
for the cube in total.
The meaning of the 3rd axis cannot always be trusted.
Although the input may seem to only support a single set of images,
using Unix pipe one can use multiple. If certain images need to be cut out
of a cube, csf(1NEMO)
can be used first. Here’s an example of these two how
to re-arrange the first 5 even and odd images into a single cube:
csf ccd1 ccd1e item=Image select=2,4,6,8,10
csf ccd1 ccd1o item=Image select=1,3,5,7,9
cat ccd1e ccd1o | ccdmerge - ccd2
csf(1NEMO)
, fitsglue(1NEMO)
, image(5NEMO)
