ML006A Correlation Report

General information

A part of C181A
no GLT or KVN participation in this subproject
Target: 3C279
Session info: http://www3.mpifr-bonn.mpg.de/div/vlbi/globalmm/
Station feedback: http://www3.mpifr-bonn.mpg.de/div/vlbi/globalmm/sessions/apr18/feedback_apr18.asc

Special processing was applied to all data in order to correlate mismatching frequency setups of ALMA and other GMVA stations. See details here.

Current Status

Correlation finished, data released on 12/12/2018.

A second data release, with a problem, spotted in the original release, corrected, was made on 31/01/2019.

A third data release, rerunning PolConvert with the latest (25.06.2019) ALMA QA2 release, was made on 01/10/2019.

Station	Code	Fringes	Plots	Comments
Ef	B	yes	Fringe overview of all baselines (all of C181A) including Ef in LL (left for each baseline) and RR (right for each baseline). Legend: white - scheduled, but no data, blue - no fringe, red-green - fringes of different quality. D -- fourfit error, in this case due to mixing upper and lower subbands in the KVN compatibility mode, no real problem with the data. c181a_FRINGE_RfAnt_Ef_LLRR_AllSrc.pdf Examples of fourfit fringe plots: c181a_No0035_3C279_AB_LL.pdf, c181a_No0035_3C279_AB_LR.pdf, c181a_No0035_3C279_AB_RL.pdf, c181a_No0035_3C279_AB_RR.pdf Same for all antennas below unless otherwise noted.	In the plots EVN is "missing" all the baselines except to ALMA. This is due to a fourfit error, the baselines are missing only from some of the diagnostic plots, but are present in the final correlation products.

For technical reasons the atmospheric correction was applied twice -- both in original ALMA data and during the correlation. Although a special procedure was developed to compensate for this, we found that its application leads to other difficulties, in particular to abnormally high fringe rate jumps, so in the final production run the double atmospheric correction was left as is.

Notes

There were problems with some diagnostic plots of this experiment due to yet poorly understood errors of fourfit and other HOPS components. But this does not change the quality of the final correlation products. (These issues were fixed in the second data release of 31/01/2019)
