Hellerschmied * quasar block scheduled automatically * APOD scans manually scheduled * Schedule summary: {{:wg7:apod:317b_sum_bearb.txt|}} * Sky plots: {{:wg7:apod:sky_317b_hb_2135-2209.pdf|}} {{:wg7:apod:sky_317b_ke_2135-2209.pdf|}} {{:wg7:apod:sky_317b_yg_2135-2209.pdf|}} * Block of 5 strong quasars were observed before and after the APOD scans * Min scan duration set to 30 sec * Sub-netting deactivated * See catalog files for full setup * 1 sec time gap in VEX files between APOD scans * Continuous tracking and recording * Min. 5 min time gap before after sat. scans to load antenna control files ===== Observation ===== * **Observers**: Jamie, Lucia, Andreas * **Comments**: ke overhead track, couldn't keep up at high elevations. Yg looked good, appeared to be stable throughout. Hb didn't look too good, weak and unstable at s-band, even at low elevation (very low elevation at Hb, slightly over 5 deg cut-off elevation). ==== Tracking ==== * Satellite tracking based on direct AzEl input files * Azel values were calculated in VieVS based on predicted WGS84 state vectors (provided by J. Sun) * Station equipment controlled by station dependent VEX files ===== Data and 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 all antennas (1 sec interval) * VEX file (station depended and combined) * VIE_SCHED files * used control + catalog files, TLEs * predicted WGS84 state vectors (1 sec interval, by J. Sun) * predicted AzEl posititons (1 sec interval, by J. Sun) * Results: * Plot showing fringe fitting results (residual multiband delays, delay rates, SNR, formal errors): {{:wg7:apod:317b.07.png?200|}} {{:wg7:apod:317b.09.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:317b.07_redclk-ion_free.vso.txt|}} {{:wg7:apod:317b.07_redclk-s.vso.txt|}} {{:wg7:apod:317b.07_redclk-x.vso.txt|}} {{:wg7:apod:317b.09_redclk-ion_free.vso.txt|}} {{:wg7:apod:317b.09_redclk-s.vso.txt|}} {{:wg7:apod:317b.09_redclk-x.vso.txt|}}
