The Very Nearby Galaxies Survey - a Herschel key program
--------------------------------------------------------

Proposal ID: KPGT_cwilso01_1
Title: "Physical Processes in the Interstellar Medium of Very Nearby Galaxies"
Principal Investigator: Christine Wilson (McMaster University)
Category: KPGT
Summary: We propose to use the SPIRE and PACS instruments on Herschel to
measure the emission spectrum from dust as well as important cooling lines
from the gaseous interstellar medium in sample of 13 very nearby galaxies
(M51, M81, NGC2403, NGC891, M83, M82, Arp220, NGC4038/39, NGC1068, NGC4151,
CenA, NGC4125, and NGC205). These galaxies have been chosen to probe as wide a
region in galaxy parameter space as possible while maximizing the achievable
spatial resolution and are already well-studied from X-ray and optical through
to radio wavelengths. The far-infrared and submillimeter wavelengths probed by
Herschel are absolutely crucial for understanding the physical processes and
properties of the interstellar medium,the interplay between star formation and
the interstellar medium in galaxies, and how they may depend on the wider
galaxian environment.

Additional Notes:

Two sets of maps are included for Cen A, M81, and M82.

M81 and M82 were SDP targets and so we provide both maps made with
larger pixels that were used for the SDP publications (Bendo et
al. 2010, Roussell et al. 2010) as well as the standard maps.

M8[1,2]*largePix.fits - SDP reduction, pixel sizes 6, 10, 14"
M8[1,2]*smallPix.fits - standard reduction, pixel sizes 6, 8, 12"

Cen A has a variable central source and so was observed a second time
with the SPIRE photometer at the same time as the SPIRE spectrometer
observation. The second observation is shallower and smaller.

cena-2C77-*.fits - deep map
cena-66AC-*.fits - smaller, shallow map
