Hi there,
I need to make cube image and I need to include whole 2GHz bandwidth. When I want to clean this cube, the clean and restor will use the beam has been made at the central frequency of 2.1GHz. I dont think I can use same beam for all 2048 channels so I need to do this in chunks and then concat the images. I tried to image 2 single channel to try imcat and imcomb but there is no success so far.
The error of imacat is : Images are not contiguous on axis 3.
The error of imcomb is : Geometry of image 1 differs from image 2, can not interpolate.
Why these errors rise and how I can make a cube with the proper beam to deconvolve.
Many Thanks,
Sara
