<div>Dear Mark Greisen,</div><div><br></div><div>I encountered a problem with FRING when I run it on a large (25Gb) VLBI line dataset.</div><div>On smaller datasets it works fine. Also the problem is only there with the TST version, not in the NEW version. I tried decreasing the solint parameter but it didn't help (see suggestions of AIPS output below). </div>
<div>Setmaxap says:</div><div><div>>setmaxap(0)</div><div>AIPS 2: SETMAXAP: current max dynamic AP is 528.000 Mbytes</div><div>AIPS 2: SETMAXAP: allowed range is 20 to 1536 Mbytes</div></div><div><br></div><div>Since I'm not sure why FRING crashes (local problems, or due to something in the program) I thought I just report it. Last week I could run FRING with similar inputs without any problems.</div>
<div>I paste the output of AIPS below together with my inputs.</div><div><br></div><div>Best regards,</div><div> Kazi</div><div><br></div><div><br></div><div><br></div><div><br></div><div>FRING2: Task FRING (release of 31DEC11) begins</div>
