IVS Analysis Report for AUM001 ($18JUL31XA) This report is the official IVS analysis report that corresponds to the database maintained by the IVS Data Centers for this session. (Analyzed by David Gordon, NASA Goddard Space Flight Center. Spoolfile source: interactive solve/nuSolve analysis.) Problems: Good session, no problems. Parameterization comments: None. Other comments: Notes from the correlator: The AUM experiments are testing the compatibility of the newly installed wideband receiver on the Hobart12 with the legacy VGOS mode. The Hb data consists of three datastreams, recorded in dual linear polarisations. These have been labelled as RCP (H-pol) and LCP (V-pol) for compatibility with FITS where initial analysis was performed.. Data were correlated using DiFX 2.5.2. Unfortunately, the version of difx2mark4 included in this release does not support the inclusion of phase cal information from additional data streams. As such, no useful phasecal information is present for the Hb station although it was recorded and extracted. Hb data were recorded using 32-MHz wide channels though the DBBC3 (X-band) and DBBC2 (S-band, using v105E firmware). Zoom bands were used to cross-correlate the data. For this reason, no LSB channels were recorded for Hb. Additionally, the upper channels of S-band (above 2.3 GHz) could not be usefully observed due to the presence of strong in-band RFI. There is a large single-band delay difference between the X- and S-band data, due to these frequencies being sent over coaxial rather than fibre, and then recorded in a difference formatter. The difference appears to be consistent and stable over the experiment. Polarisation combination was accomplished through solving for single band delays and phases separately and then fringe fitting the Hb baselines with the "-PRR+RL" options in fourfit. ----------------------------------------- Session Statistics Observations: 1404 scheduled 1386 correlated (in database) 1358 recoverable (usable) 1321 used Session fit: 42.287 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HOBART12 936 909 890 95.1% KATH12M 936 909 889 95.0% YARRA12M 936 898 863 92.2% --------------- --------- ----------- --------- ------ Station Total** 1404 1358 1321 94.1% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
