MM013B Correlation Report

General information

A part of C181C
No ALMA participation in this part
Targets: 3C84, 3C111, 3C120, 0836+710, 0954+658, 0716+714, 3C454.3, CTA102
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
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, data is ready to be released.

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. c181c_FRINGE_RfAnt_Ef_LLRR_AllSrc.pdf Examples of fourfit fringe plots: 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.
On	X	yes	c181c_FRINGE_RfAnt_On_LLRR_AllSrc.pdf	in the plots On 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.
Ys	Y	yes	c181c_FRINGE_RfAnt_Ys_LLRR_AllSrc.pdf	As usual, Ys observed LCP only, but it was also recorded as fake RCP, that's why there are common Ys "right" to other antenna's left fringes. in the plots Ys 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.
Mh	Z	yes	c181c_FRINGE_RfAnt_Mh_LLRR_AllSrc.pdf	in the plots Mh 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.
Pv	P	yes	c181c_FRINGE_RfAnt_Pv_LLRR_AllSrc.pdf	in the plots Pv 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.
VLBA: Br	b	yes	c181c_FRINGE_RfAnt_Br_LLRR_AllSrc.pdf	Baselines to EVN stations are "missing" due to a fourfit error. They are present in the final correlation products.
VLBA: Fd	f	yes	c181c_FRINGE_RfAnt_Fd_LLRR_AllSrc.pdf	Baselines to EVN stations are "missing" due to a fourfit error. They are present in the final correlation products.
VLBA: Kp	k	yes	c181c_FRINGE_RfAnt_Kp_LLRR_AllSrc.pdf	Baselines to EVN stations are "missing" due to a fourfit error. They are present in the final correlation products.
VLBA: La	l	yes	c181c_FRINGE_RfAnt_La_LLRR_AllSrc.pdf	Baselines to EVN stations are "missing" due to a fourfit error. They are present in the final correlation products.
VLBA: Mk	m	yes	c181c_FRINGE_RfAnt_Mk_LLRR_AllSrc.pdf	Baselines to EVN stations are "missing" due to a fourfit error. They are present in the final correlation products.
VLBA: Nl	n	yes	c181c_FRINGE_RfAnt_Nl_LLRR_AllSrc.pdf	Baselines to EVN stations are "missing" due to a fourfit error. They are present in the final correlation products.
VLBA: Ov	o	yes	c181c_FRINGE_RfAnt_Ov_LLRR_AllSrc.pdf	Baselines to EVN stations are "missing" due to a fourfit error. They are present in the final correlation products.
VLBA: Pt	p	yes	c181c_FRINGE_RfAnt_Pt_LLRR_AllSrc.pdf	Baselines to EVN stations are "missing" due to a fourfit error. They are present in the final correlation products.
GBT: Gb	G	yes	c181c_FRINGE_RfAnt_Gb_LLRR_AllSrc.pdf	Baselines to EVN stations are "missing" due to a fourfit error. They are present in the final correlation products.
GLT: Gl	g	yes	c181c_FRINGE_RfAnt_Gl_LLRR_AllSrc.pdf ______________________________________________________________	Did not participate in any of the scans of this part.

KVN: Ky	y	yes	c181c_FRINGE_RfAnt_Ky_LLRR_AllSrc.pdf

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.

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 3 different fits files, see their content below in the pclist section.
