MG004 Correlation Report

General information

A part of C181D
Targets: OJ287, 1055+018
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 is ready to be released.

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: c181d_No0038_1055+018_AB_LL.pdf, c181d_No0038_1055+018_AB_LR.pdf, c181d_No0038_1055+018_AB_RL.pdf, c181d_No0038_1055+018_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. 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.

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.

They are present in the final correlation products. Taken out for several scans because of USNO observing. General performance in c181d poor, with fringes mostly to ALMA.

They are present in the final correlation products. For most of this experiment: unrecoverable read error of the Mk5 module, logs indicate bad weather, so this loss is considered non-critical

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 product.

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.

For technical reasons the correlation output is saved as 4 different fits files, see their content below in the pclist section.
