File contents

This README file contains a description of single quasar stare data
taken in the past long baseline tests/campains.  These data were
taken as "commissioning data," so that there is no script for data


The list of the data with observation date, ExecBlock name, PWV,
observation band, source name, longest baseline, and notes is written
in 10kmBL-DataStatus.pdf.

The data in the list have been observed by a manual command just to
observe a single strong quasar without doing any calibration.  This
is to check and study the stability/fluctuation of amplitude and
phase of the system and/or the atmosphere.  The data have been taken
at the long baseline tests/campaigns in 2012 (2 km baseline test),
2013 (3 km baseline test), and 2014 (10-15 km baseline campaign).
All the data are taken in Time Domain Mode (TDM) with both XX and YY
polarizations and 4 basebands (BBs) with 2 GHz bandwidth for each BB.
Frequency bands that have been used are Bands 3, 6, 7, 8 and 9.
Integration time for each data point is about 1 second, and the total
observation time were varied data by data, from about 10 minutes to
up to 40 minutes.  Number of antennas that have been used were also
varied data by data, from about 10 antennas to up to about 40
antennas.  Further details of the observations are in the list.

Due to the commissioning purpose of the data taking, various problems
can be in the data, such as amplitude/phase jumps, water vapor
radiometer problems, undetermined pad positions, etc., which needs to
be carefully examined when using these data.  Furthermore, since
there is no calibration information as mentioned above, all the
values in the data are arbitrary.

Publications making use of these data must include the following
statement in the acknowledgement:
