Abstract:
This paper involves a data release of the observational campaign:
Cosmicflows with Spitzer (CFS). Surface photometry of the 1270
galaxies constituting the survey is presented. An additional ∼400
galaxies from various other Spitzer surveys are also analysed. CFS
complements the Spitzer Survey of Stellar Structure in Galaxies, that
provides photometry for an additional 2352 galaxies, by extending
observations to low galactic latitudes (|b|<30°). Among these
galaxies are calibrators, selected in the K band, of the Tully-Fisher
relation. The addition of new calibrators demonstrates the robustness
of the previously released calibration. Our estimate of the Hubble
constant using supernova host galaxies is unchanged,
H0=75.2±3.3km/s/Mpc. Distance-derived radial peculiar velocities,
for the 1935 galaxies with all the available parameters, will be
incorporated into a new data release of the Cosmicflows project. The
size of the previous catalogue will be increased by 20 percent,
including spatial regions close to the Zone of Avoidance.
Description:
The post-basic calibrated data of the 1270 observed galaxies for the
CFS programme are available at the Spitzer Heritage Archive. Every
galaxy has been observed with the first channel of the IRAC instrument
where a point spread function with a FWHM=1.66arcsec is sampled with
1.2arcsec/pixels. The field of view is 5.2x5.2arcmin2 which is
adequate to include most galaxies beyond twice their diameter at the
25th isophote (mag/arcsec2) in the B band.
