Improving the u-v coverage Quickest possible summary of papers Calibration Results
Svetloe Zelenchukskaya Badary movie: www.ipa.nw.ru/PAGE/ENG/film/film.htm 1st EVN experiments = EK028A-C (Oct’08) Officially joined EVN in Nov’09 Regular user experiments since Mar’10 session
EVN user experiments with at least one KVAZAR station - Abandoned experiments not counted (5 total)
- Half-integral = one band of multi-band (RadioAstron) obs
- Target-of-opportunity & out-of-session included (12 total)
3 declinations (65, 35, 05) 3 declinations (65, 35, 05) 3 bands (6cm, 3.6cm, 1.3cm) u-v coverage plots for 12-hr observations - With & without the KVAZAR stations (highlighted in red)
- 24-hr for the low-declination case (3.6cm, no Wb)
in refereed journals only (no conferences, no arXiv) in refereed journals only (no conferences, no arXiv) Culled from the JIVE Biennial reports - Appendix “Publications based on EVN data”
- Separate columns for some observations KVAZARs can’t do (yet)
- This categorization done “by eye” (from the title, from prior knowledge,….)
- Also excluded the papers based on global 7mm observations without a separate column
- 2013-4 from ADS private library started to collect EVN pubs
- Did not read through these to confirm KVAZR participation
- Characteristic of VLBI papers: long latency after observation
Self-cal in pipeline (NMEs + user experiments) provides amplitude-gain corrections (AGC) per source Self-cal in pipeline (NMEs + user experiments) provides amplitude-gain corrections (AGC) per source Median AGC compiled per EVN session Table 1: analog back-end (pre-R1002) - Station Order = Sv/Zc/Bd; tabulated median-AGC = x100
Table 2: digital back-end (R1002) Table 2: digital back-end (R1002) - Station Order = Sv/Zc/Bd; tabulated median-AGC = x100
- Clearly bad IFs excised (6cm Sv RCP [2/13], warm LCP [3/13])
