This README file contains a description of the Pluto Observation
taken in Band 7 in support of the NASA New Horizons Mission.  These
data were taken as "test data" and contain basic scripts for
calibration and imaging. Additional ALMA Science Verification data,
scripts and data products and be found off the ALMA Science Portal at:

Each directory contains a the reduction/imaging script of the form:
     pluto_nov_25.py etc

The asdm is also included.   The other files were made by executing
the python script and will be overwritten when rerun.

To execute and rerun the reduction and imaging script simply type:

CASA>execfile('pluto_nov_25.py')

at the CASA command prompt.

These data were calibrated and imaged using CASA Version 4.4.0-REL (r33623)

The major goal of the observations were to determine the position
and parallax of the Pluto system.  Each observation consisted
primarily of phase referencing observations between the calibrator
J1911-2006 and Pluto with a secondary calibrator J1924-2105.  The
phase cycle time was about 7 min, with 5.5 min scan on Pluto, and the
total experiment extent was 80 min.  The longest baseline was about
500 m.  Four spw's were used, each of 2 GHz, centered at 336, 338,
348, 350 GHz.  The strong calibrator J1924-2914 was used as the
bandpass calibrator and the absolute flux density calibrator.  It is
monitored frequency with ALMA and its flux density is known to about
5-10% accuracy for most of the experiments.  The script uses
J1911-2006 as the phase calibrator for Pluto, and continuum images of
the Pluto/Charon system were obtained over the entire bandwidth.  No
special astrometric calibrations or spectral information are included
in the script.
