<p>Thanks Eric for these explanations!</p>
<p><br>
</p>
<p>Just tried without running INDXR after loading the data with
FITLD, and it seems to be ok. So my new pipeline looks like: FITLD
> ANTAB > USUBA > INDXR, and I hope I am not loosing
data or scans in the way...</p>

The reason that FITLD deletes the CL and NX tables when it
discovers a subarray condition is that it cannot correctly
determine an NX table. The same is true of INDXR. INDXR works
correctly only after USUBA. I am guessing that ANTAB will not
work without an NX table. But the logic of USUBA is nasty also
(I was never able to debug this task) so running USUBA is really
needed at the beginning.</div>

<p>Hello Eric,</p>
<p><br>
</p>
<p>Indeed, when running FITLD > USUBA > INDXR, I see the
CL entry for source 4 subarray 2!</p>
<p><br>
</p>
<p>What I use to do in my pipeline is:</p>
<p>FITLD > INDXR > ANTAB (to import tsys/gain for non-VLBA
stations ; easier to deal there since there is only one
subarray) > USUBA > INDXR (to get the subarray info
correctly in CL/NX...)<br>
</p>
<p><br>
</p>
<p>I just tried FITLD > INDXR, and the CL entries for source
4 around 17:40 are already gone.</p>
<p><br>
</p>
<p>Do you know why? Do you recommand to proceed with USUBA the
earliest in the processing pipeline?</p>
<p><br>
</p>
<p>Cheers,</p>

I loaded RV158, ran USUBA, and then INDXR. With
CPARM(3)=0.15 and CPARM(4)=1, INDXR made a CL table with
13127 rows including a great many for source 4 subarray 2 in
the time range 17:38:10 to<br>
17:43:34. In PRTAB INEXT='CL',rparm 3 1 4 0.1 5 1 2 0.1;

<p>Hello Eric, Amy,</p>
<p>I am analysing the global VLBI session RV158 (VLBA + 8 IVS
antennas ; 24h ; S/X-band ; available at NRAO data archive).</p>
<p>I'm looking at the source 0403-132 (#4 in my data), which
is in the index as:</p>
<p> 4 0/17:40:52.0 00:05:24.0 4
2 9992 14396</p>
<p>(as you can see, I have subarrays in my dataset)</p>
<p>For this scan, there is data (checked with VPLOT).</p>
<p>However, this scan is NOT in CL1, which was created after
loading the data (FITLD) by runnig INDXR. CL1 was
(normally?) updated after running USUBA by running INDXR
again.</p>
<p><i>How is that possible? Any clue why this scan is not in
CL1?</i></p>
<p>Moreover, I am building SN1 from TY1/GC1, and I have gain
amplitude values for this scan. Is there a way to get this
into CL2 (with CLCAL)? Or since there is not row in CL1 for
this scan, no hope to get it in CL2?</p>
<p>Thanks in advance for your help!</p>
<p>Best wishes,</p>
<p>Arnaud</p>
