Hello,<br>I have installed aips08 in linux(CentOS).<br>i ran imagr and created an image with 59 facets.i am using FLATN to <br>put together these facets.FLATN is running extremely slowly(more than 5 times slower) compared to <br>
what it used to in DEC05 version.i am copying the FLATN inputs :<br>AIPS 1: FLATN: Re-grid multiple fields and pointings to one image<br>AIPS 1: Adverbs Values Comments<br>AIPS 1: ----------------------------------------------------------------<br>
