An initial run of CLEAN has been performed on the KCM51_4+25B7 image, and the results are shown below in contour and greyscale form, the dirty image as already presented is shown on the left and the CLEAN image shown on the right. The parameters used in IMAGR are listed immediately below, with main points including gain 0.1, number of iterations 20000, and CLEAN box equal to the image size as displayed. which in effect means that the A array has a 1024x1024 CLEAN box, and for the C and E arrays the box size scales as the inverse of the pixel scale.
