DESCRIPTION:Speakers: Dr. VARENIUS\, Eskil (Chalmers University of Technol
 ogy)\nIn this talk I will present some preliminary results on fringe-tests
  done with the Oe-Ow baseline at frequencies above the usual VGOS band D. 
 I will discuss what changes are needed compared to our "standard" VGOS sys
 tem\, and some ideas for how to deal with potential issues such as faint P
 CAL at high frequencies.\n\nhttps://events.mpifr-bonn.mpg.de/indico/event/

SUMMARY:OTT quasar flux monitoring and amplitude calibration stability

DESCRIPTION:Speakers: Dr. VARENIUS\, Eskil (Chalmers University of Technol
 ogy)\nI will present results from a recent campaign to measure quasar flux
  densities using the single ONSA13SW (Ow) and ONSA13NE (Oe) 75m baseline. 
 During 2021 we conducted more than 60 short (20m) experiments in order to 
 measure flux densities of a few bright sources. The aims were to a) check 
 and monitor the Oe and Ow RF stability in the long and short term\, b) ass
 ess the feasibility of doing regular flux monitoring using this single bas
 eline\, and c) verify recent DBBC3 multicast amplitude calibration feature
 s added to the VLBI Field-system version 10.\n\nhttps://events.mpifr-bonn.

SUMMARY:Current status and future plans for VieSched++

DESCRIPTION:Speakers: SCHARTNER\, Matthias (ETH Zurich)\nWithin this prese
 ntation\, we will give a brief overview of the development status of the V
 LBI scheduling software VieSched++ as well as show our future plans. The l
 ast bigger update was published end of April and was related to integratin
 g satellite observations. Since then\, development has focused on smaller 
 bug fixes and increased automation for operational use. \nThe next bigger 
 update is planned to incorporate VEX2 support in VieSched++. Currently\, t
 he use of .skd files instead of .vex files is a significant limitation in 
 geodetic VLBI - especially for VGOS where it is almost impossible to gener
 ate new schedules without extensive expert knowledge. \nWith the enhanced 
 support of VEX2\, it is required to also define new scheduling catalogs. T
 he current sked-catalogs have a large number of limitations and several wo
 rkarounds are necessary for both\, SX and VGOS sessions. Many of those wor
 karounds are not even documented. \nThis talk aims to provide some backgro
 und information to initiate further discussions regarding a transition fro
 m .skd to .vex files\, improvements in scheduling\, as well as new catalog
  designs.\n\nhttps://events.mpifr-bonn.mpg.de/indico/event/194/session/27/
