MM013A Correlation Report
General information
- A part of C181A
- Targets: OJ287, 3C345, 1510-089, 1633+38, 0235+164, 3C120
- 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 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. Examples of fourfit fringe plots: preliminary: c181a_No0055_3C345_BP_LL.pdf, c181a_No0055_3C345_BP_LR.pdf, final: Same for all antennas below unless otherwise noted. | |

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