IVS Analysis Report for AUM002 ($18AUG01XA) 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: Correlator comments: 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. Unlike the processing of AUM001, this delay has not been accounted for in the fringe-fitting. 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: 1446 scheduled 1417 correlated (in database) 1412 recoverable (usable) 1388 used Session fit: 40.737 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HOBART12 964 941 930 96.5% KATH12M 964 941 924 95.9% YARRA12M 964 942 922 95.6% --------------- --------- ----------- --------- ------ Station Total** 1446 1412 1388 96.0% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
