<div dir="ltr">Hi all,<div><br></div><div>Yes Stuart has been in contact about supporting it in jive5ab. The raw samples seem to be simple enough to decode in themselves, but what I suspect is, that due to its non-framed format, decoding it might be more tricky than anticipated (I know several bits of code in jive5ab are firmly built on the assumption that the data is a stream of relatively small/finite size frames, each with a header and a payload and that, possibly, really big frames, might break those assumptions).</div><div><br></div><div>Looking at the spec (<a href="https://public.ccsds.org/Pubs/506x1b1.pdf">https://public.ccsds.org/Pubs/506x1b1.pdf</a>) - or what I believe to be the "RDEF" spec - the question is: what do you _actually_ mean by supporting RDEF? The code being able to read an observation file and process all the product files in one fell swoop? (For the jive5ab case: how would like like RDEF support to /look/ like? For a correlator running off a config file with file names in it that the multitude of RDEF product files seem a natural match, but for jive5ab much less so.)<br><br>Personally, I think it might be worthwhile checking if support for RDEF could be built into the "baseband" package (<a href="https://baseband.readthedocs.io/en/stable/index.html">https://baseband.readthedocs.io/en/stable/index.html</a>). It's Python and associated w/ astropy (lots of useful basic tools already available) and for translating/filtering VLBI data it might be a more natural place.</div><div><br></div><div>Cheers,</div><div>M</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, 8 Oct 2024 at 02:10, Stuart Weston via Difx-users <<a href="mailto:difx-users@listmgr.nrao.edu">difx-users@listmgr.nrao.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Thanks Adam,</div><div><br></div><div>I have been corresponding with Marjolein Verkouter on jive5ab -> rdef. <br></div><div><br></div><div>Stuart<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Oct 8, 2024 at 12:56 PM Adam Deller <<a href="mailto:adeller@astro.swin.edu.au" target="_blank">adeller@astro.swin.edu.au</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Hi Stuart.</div><div><br></div><div>No-one has implemented native support for RDEF as far as I know. I had an email exchange from Christopher Volk from JPL (<a href="mailto:christopher.p.volk@jpl.nasa.gov" target="_blank">christopher.p.volk@jpl.nasa.gov</a>) about RDEF a couple of years ago. At the time I advised him to use a converter, but you could follow up to see if he investigated native support. I think it would certainly be possible, but not a quick 30 minute job to add it to mark5access. (Also not sure whether jive5ab supports it, which might enable you to at least do it on the fly at correlate time).<br></div><div><br></div><div>Cheers,.</div><div>Adam<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, 8 Oct 2024 at 08:46, Stuart Weston via Difx-users <<a href="mailto:difx-users@listmgr.nrao.edu" target="_blank">difx-users@listmgr.nrao.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Spent a bit of time searching through the wiki and documentation looking for Raw Data Exchange format (RDEF) support.
