Hellerschmied * quasar block scheduled automatically * APOD scans manually scheduled * Schedule summary: {{:wg7:apod:318c_sum.txt|}} * Block of 4 strong quasars was observed prior to APOD * Min scan duration set to 40 sec * Sub-netting deactivated * See catalog files for full setup * 1 sec time gap in VEX files between APOD scans * Continuous tracking and recording ===== Observation ===== * Observers: Jamie, Lucia * Comments: Hb and Ke went fine. Unfortunately sattrack didn't want to run on the 26m ==> No data recorded at Ho ==== Tracking ==== * Satellite tracking based on direct AzEl input files at {{:wg7:apod:318c_sum.txt|Hb}}, {{:wg7:apod:kath12m_2016_11_13_21_13_05_trf.txt|Ke}}, {{:wg7:apod:hobart26_2016_11_13_21_20_01_trf.txt|Ho}} * Azel values calculated in VieVS based on predicted APOD state vectors (pos. + vel., WGS84) provided by J. Sun * Station equipment controlled with station dependent VEX files ===== Available files ===== * All control files used for the observations (VEX schedules, schedule summaries, orbit files, AzEl tracking files, etc.) are provided on the VieVS server (''sorts@vievs.hg.tuwien.ac.at'') at ''/home/sorts/apod/2016/'' * Azel tracking files for Ho, Hb, Ke * VEX file (station depended and combined) * VIE_SCHED files * used control + catalog files * predicted WGS84 state vectors (1 sec interval, by J. Sun) * predicted AzEl posititons (1 sec interval, by J. Sun) * final orbit solution (accuracy still less than 30 m according to J. Sun) * GCRF state vectors (pos. + vel.), 1 sec interval * WGS84 state vectors (pos. + vel.), 1 sec interval * Results: * Plot showing fringe fitting results (residual multiband delays, delay rates, SNR, formal errors): {{:wg7:apod:318c.06.png?200|}} * VSO observation files containing the multiband total delays calculated by HOPS/fourfit (remove the .txt file name extension to load the VSO files in VieVS): {{:wg7:apod:318c.06_redclk-ion_free.vso.txt|}} {{:wg7:apod:318c.06_redclk-s.vso.txt|}} {{:wg7:apod:318c.06_redclk-x.vso.txt|}}
