Abstract:
We provide an overview of ancillary 24, 70, and 160 micron data from
the Multiband Imaging Photometer for Spitzer (MIPS) that are intended
to complement the 70-500 micron Herschel Space Observatory photometry
data for nearby galaxies obtained by the Herschel-SPIRE Local Galaxies
Guaranteed Time Programs and the Herschel Virgo Cluster Survey. The
MIPS data can be used to extend the photometry to wave bands that are
not observed in these Herschel surveys and to check the photometry in
cases where Herschel performs observations at the same wavelengths.
Additionally, we measured globally-integrated 24-160 micron flux
densities for the galaxies in the sample that can be used for the
construction of spectral energy distributions. Using MIPS photometry
published by other references, we have confirmed that we are obtaining
accurate photometry for these galaxies.
Description:
The 24-160 micron Spitzer MIPS data supplement the 70-500 micron
Herschel data that have obtained by the Herschel-SPIRE Local Galaxies
Guaranteed Time Programs (the Very Nearby Galaxies Survey, the Dwarf
Galaxies Survey, and the Herschel Reference Survey) and the Herschel
Virgo Cluster Survey.

Global notes:
Note (G1): The HRS number corresponds to the numbers given by Boselli
et al. (2010PASP..122..261B 2010PASP..122..261B), <[BEC2010] HRS NNN> in Simbad.
Note (G2): The coordinates are taken from the NASA/IPAC Extragalactic
Database unless otherwise noted.
Note (G3): The dimensions and position angle of the optical discs are
taken from Third Reference Catalogue of Bright Galaxies by de
Vaucouleurs et al. (Cat. VII/155). The flux densities were
generally measured within regions that are 1.5 times the size of
the optical disc parameters given here. When the major axis,
major/minor axis ratio, and position angle are specified by de
Vaucouleurs et al. (1991, Cat. VII/155), then all of that data is
printed here, and the source is treated as elliptical for photometry.
If de Vaucouleurs did not specify the major/minor axis ratio or the
position angle of the optical disc, then only the major axis is
given, and the optical disc is treated as a circular disc for
photometry. If the major axis is not specified, then the source
is treated as a point source for photometry. The position angle
is defined as degrees from north through east.
Note (G4): Flags are as follows:
A = Flux densities for these objects were measured in special
apertures other than the standard photometry apertures
(1.5 times the optical disc of the galaxies), but the central
coordinates of the aperture still correspond to the coordinates
given in the NASA/IPAC Extragalactic Database.
B = Either these objects are composed of two or more sources with
optical discs that overlap or are one of the objects within
such systems. Flux densities were measured within special
apertures that encompassed the emission from all overlapping
sources. The reported coordinates correspond to the center of
the apertures used for photometry and not necessarily to the
positions of the sources as given by the NASA/IPAC
Extragalactic Database. Note that one set of flux densities
is reported for NGC 4567 and NGC 4568.
C = Flux density measurements were made within the optical discs
of these sources instead of within regions that were 1.5 times the
size of the optical discs.
Note (G5): Flags are as follows:
A = The 160 micron measurements are from data in which significant
portions of the optical discs (>10%) of the galaxies were not
covered in this specific wave band. The measurements here are
for the region that was covered in the MIPS data. We have
applied no corrections for the missing flux density.
B = These 160 micron measurements are for galaxies that were
covered in scan map observations in which the final 160 micron
images for these galaxies contain NaN values within the
optical disc as a consequence of incomplete coverage. This
typically occurs when scan maps are performed using the fast
scan rate, although NaN values within the optical discs of
galaxies occasionally appear in other data. The 160 micron
measurements for these galaxies is based upon interpolating
over these pixels.
