Abstract:
We have analyzed a sample of nearby cool and warm infrared (IR)
galaxies using photometric and structural parameters. The set of
measures include far-infrared color [C=log(S60um/S100um)], total
IR luminosity (LFIR), radio surface brightness, and radio,
near-infrared, and optical sizes.

Note (1): Galaxy class as follows:
SFGs = Low Luminosity Star Forming Galaxies
LIRGs = Luminous Infrared Galaxies
ULIRGs = Ultra-Luminous Infrared Galaxies
Galaxies identified as [RHM2006] Class Seq,
i.e. [RHM2006] SFGs 1 for NGC 4565
Note (2): Galaxies are sorted in the ascending order of FIR color,
i.e. galaxy numbered 1 has the lowest FIR color, for all three
luminosity classes.
Note (4): Peak flux Sp in Condon, Anderson & Helou (1991ApJ...376...95C 1991ApJ...376...95C).
Sp in mJy in the VLA map with the beam of VLA map, selected by
"the maximum at which the source is resolved" (Wang & Helou,
1992ApJ...398L..33W 1992ApJ...398L..33W).
* For IRASF12224-0624 (LIRGs) Condon, Anderson & Helou
(1991ApJ...376...95C 1991ApJ...376...95C) gives θM*θm<5arcsec2.
We assume θM∼5arcsec.
* For IRASF15250+3608 (ULIRGs) Condon, Anderson & Helou
(1991ApJ...376...95C 1991ApJ...376...95C) gives θM*θm<0.3arcsec2.
We assume θM∼0.3arcsec.
Note (5): The following flags from Revised Bright Galaxy Catalog (RBGS)
of Sanders et al. (2003, Cat. J/AJ/126/1607):
P = Distance is not computed by correcting the heliocentric redshift
using the cosmic attractor model, but comes from a direct
primary distance measurement
S = A direct secondary distance measurement
V = The cosmic attractor flow model places the object within the
Virgo Cluster at a distance of 15.3Mpc
Note (6): The following 22 SFGs have either disturbed outer envelope or a
nearby companion (after visual inspection):
NGC5792, UGC12914, NGC5600, NGC5937, NGC3508, NGC4045, NGC5430, NGC3994
NGC5218, NGC0150, NGC1134, NGC1083, NGC0660, NGC5953, NGC4532, NGC5915,
NGC0520, NGC2782, NGC5930, NGC2798, NGC3597, NGC1222
The following 15 LIRGs have either disturbed outer envelope or a
nearby companion (after visual inspection):
NGC5394, NGC5257, UGC04881, MCG+07-23-019, NGC6052, NGC6090,
CGCG247-020, NGC5256, NGC7592, IRASF17132+5313, IRASF03359+1523, NGC2623,
