<p class="xmsonormal"><span style="font-size:11.0pt">I have text installed AIPS 2023 on my Macbook Pro and it’s running smoothly. I am encountering a problem while running the task FLATN. Here I want to interpolate 25 fields into one as I have performed a wide-field
imaging (610 MHz data from GMRT telescope in India). The problem is that the task starts but doesn’t finish no matter how long I let take and I need to abort to get the terminal back. The resulting FLATNed image is junk without any intensities.</span><o:p></o:p></p>
