These data represent the PHIBSS first-phase public data release. Data
cubes, integrated intensity maps and velocity spectra are available
for 32 galaxies.

CONTENTS

This release includes eight files for each galaxy:

NAME-co32.aipsfits   - the uv-table by spectral channel (aips fits format)
NAME-co32.uvt        - the uv-table by spectral channel (gildas format)
NAME-co32.fits       - the line integrated uncleaned table (fits format)
NAME-co32.lmv        - the line integrated uncleaned map (gildas format)
NAME-co32-clean.fits - the line integrated cleaned map (fits format)
NAME-co32.lmv-clean  - the line integrated cleaned map (gildas format)
NAME-co32.dat        - spectral data (ascii table)
NAME-co32.eps.gz     - spectral profile and line-integrated map

The filename contains in general the abbreviated target identification
(NAME).  Observations were all made in the 3-2 transition of the main
isotopic form of carbon monoxyde.

UNITS

The data should be ready to use for science as they are, without
corrections. That is, units are Jy for the uv-tables and Jy/beam for
the dirty maps. Velocities are in units of km/s, frequencies are in
MHz, positions in radians.

METHOD

The data cubes have been reduced mostly as described in Tacconi et
al. (2010). Zero-moment uv-tables, dirty and cleaned maps were
constructed by integrating over the line profiles as to achieve the
maximum signal to noise ratio. Data cubes and maps were cleaned using
the Clark algorithm and a number of clean component adapted to noise.

The spectral data were extracted from the uncleaned data cubes at the
position of the peak in the line-integrated uncleaned map and by
integrating over the cleaned emission region when the targets were
found to show extended emission.
