MM013C Correlation Report
General information
- A part of C181D
- No ALMA participation in this part
- Targets: BLLAC, 2013+370
- 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
- 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 - Because this experiment was processed together with ALMA observations, special processing was applied to all data in order to correlate mismatching frequency setups of ALMA and other GMVA stations. See details here. This should not have infuenced non-ALMA scans.
Current Status
Correlation finished, released on 10/12/2018.
A second data release, with a problem, spotted in the original release, corrected, was made on 31/01/2019.
Fringes
| Station | Code | Fringes | Plots | Comments |
|---|---|---|---|---|
| Ef | B | yes | Fringe overview (including all of C181D) of all baselines 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 18-20, 24-26, 28-29, 31, 33, 35-36 are missing from all diagnostic plots due to a difx2mark4 error. They are present in the final correlation products. c181d_FRINGE_RfAnt_Ef_LLRR_AllSrc.pdf Examples of fourfit fringe plots: Diagnostic fringe plots only to KVN due to a fourfit problem. c181d_No0052_2013+370_Bt_RL.pdf, c181d_No0052_2013+370_Bt_RR.pdf, c181d_No0052_2013+370_Bu_RL.pdf, c181d_No0052_2013+370_Bu_RR.pdf, c181d_No0052_2013+370_By_RL.pdf, c181d_No0052_2013+370_By_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.

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 product. (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.
