On the uvfits file that I convert from OIFITS, it seems I cannot have VPLOT working properly. No matter which parameter I've chosen, I alway get messages like:</div><div class=""><br class=""></div><div class=""><div class="">LOCALH> VPLOT1: Task VPLOT (release of 31DEC17) begins</div><div class="">LOCALH> VPLOT1: ANREFM: NO ANTENNA OR ARRAY RECOGNIZED</div><div class="">LOCALH> VPLOT1: ANREFM: NO ANTENNA OR ARRAY RECOGNIZED</div><div class="">LOCALH> VPLOT1: ANREFM: NO ANTENNA OR ARRAY RECOGNIZED</div><div class="">LOCALH> VPLOT1: UVGET: doing no flagging this time</div><div class="">LOCALH> VPLOT1: FOUND 0 POINTS: NOT ENOUGH TO SELF-SCALE</div><div class="">LOCALH> VPLOT1: Appears to have ended successfully</div><div class="">LOCALH> VPLOT1: localhos 31DEC17 TST: Cpu= 0.0 Real= 0 IO= </div><div class=""><br class=""></div><div class="">However, I've tried this data with UVPLT and it worked fine (e.g. for a uv-coverage plot). I've also tried VPLOT on other VLBI data and it worked fine, either. So I'm quite confused why VPLOT doesn't work on my converted data. Since I'm trying to overlay our CC model on the vis. data, VPLOT is quite important for us. </div><div class=""><br class=""></div><div class=""><div class="">BTW, my AIPS version is 31DEC17. I've tried VPLOT both on a mac and on a linux machine, neither worked for my converted data.</div></div><div class=""><br class=""></div><div class="">Could you try on my data and see if you can plot any plots with VPLOT? I've attached our test data below. Thank you!</div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Best regards,</div><div class=""><br class=""></div><div class="">Feng</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""></div></div></body></html>
