General Comments. ( Brief data summary and scan listing )
RB005, C-band VLBI experiment on 2019 March 13, 6.7 GHz setup. The data rate was 128 Mbps (1 x 16 MHz subbands, dual polarization, two-bit sampling). The target source G358 was calibrated using the phase-reference sources J1744-3116 and J1743-3058. 3C273, 3C279, OQ208, J1635+3808, BLLAC were also observed as calibrators and fringe finders.
7 stations participated.


Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations.


Plots of the uncalibrated amplitude and phase against time
Comments.
Full-experiment for Sr-** baselines, no calibration applied. A 1.0 minute plot-averaging was used.


Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Scalar averaged Sr-** baselines, each scan plotted separately. No calibration applied yet.


The uncalibrated amplitude and phase of the crosshand correlations against frequency channel
Comments.


TSYS against time
Comments.
TY1 table, each IF/pol on a separate plot.


Telescope sensitivities from the a priori TSYS and Gain curves (the square of this number gives the antenna noise (SEFD) in Jy - the smaller the better).
Comments.
Gain amplitude from CL2 table.


Fringe-fit phase solutions (including Parallactic Angle correction).
Comments.
CL3 station phase solutions -- CL3 = CL2+SN2, thus also includes the initial amplitude/parallactic angle calibration from CL2 and the fringe solutions from SN2.


Fringe-fit delay solutions
Comments.
SN2 station delay solutions for the fringed sources, each IF/pol on a separate plot.


Fringe-fit rate solutions
Comments.
SN2 station rate solutions.


Telescope bandpasses
Comments.
Bandpass table 1. J2202+4216 and 3C48 were used for bandpass calibration.


Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Full-experiment for Sr-** baselines, calibrated with CL3. The 1.0-min plot-averaging still applied.


Calibrated amplitude and phase against frequency channel
Comments.
Sr-** baselines calibrated with CL3 and BP1. The amp and phase plots self-scale, not necessarily going down to 0 in the case of the amps.
