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.

              did not observe.
  NOT CORR:   Baseline was scheduled but not correlated.
  NO DATA:    The baseline's stations were both correlated,
              but they did not observe together.
