- Targets: M87, 3C273, 3C279
- Session info: http://www3.mpifr-bonn.mpg.de/div/vlbi/globalmm/

- GBT calibration info (Tsys files for download) and other related information for this session can be found here:
https://safe.nrao.edu/wiki/bin/view/GB/Observing/WbandVLBACal/C181 - 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 10/12/2018.
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 26/09/2019.
Fringes
| Station | Code | Fringes | Plots | Comments |
|---|---|---|---|---|
| Ef | B | yes | Fringe overview of all baselines (all of C181C) 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. Scans 30, 33, 77-78, 80, 82-83, 92 are missing from all diagnostic plots due to a difx2mark4 error. They are present in the final correlation products. c181c_FRINGE_RfAnt_Ef_LLRR_AllSrc.pdf Examples of fourfit fringe plots: c181c_No0075_3C279_AB_LL.pdf, c181c_No0075_3C279_AB_LR.pdf, c181c_No0075_3C279_AB_RL.pdf, c181c_No0075_3C279_AB_RR.pdf Same for all antennas below unless otherwise noted. | in the plots Ef is "missing" all the baselines except to ALMA, GLT and KVN.

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)
GLT participated in this session for the first time as a test, and serious problems were detected when analysing its data. Be very carerful when using them.
