Abstract:
We present photometrically calibrated images and surface photometry in
the B, V, R, J, H, and K bands of 25, and in the g, r, and K bands of
five nearby bright (B0T<12.5 mag) spiral galaxies with
inclinations of 30°-65° spanning the Hubble sequence from Sa
to Scd. Data are from The Ohio State University Bright Spiral Galaxy
Survey (Eskridge et al., Cat. J/ApJS/143/73), the Two Micron All Sky
Survey (2006AJ....131.1163S 2006AJ....131.1163S), and the Sloan Digital Sky Survey Second
Data Release (Abazajian et al., 2004AJ....128..502A 2004AJ....128..502A). Radial surface
brightness profiles are extracted, and integrated magnitudes are
measured from the profiles. Axis ratios, position angles, and scale
lengths are measured from the near-infrared images. A one-dimensional
bulge/disk decomposition is performed on the near-infrared images of
galaxies with a nonnegligible bulge component, and an exponential disk
is fit to the radial surface brightness profiles of the remaining
galaxies.

Note (1): Flag on Name, defined as follows:
b = All imaging is from SDSS DR2 (Abazajian et al.,
2004AJ....128..502A 2004AJ....128..502A) and 2MASS.
d = All imaging is from Verheijen (1997, Ph.D. thesis,
Rijksuniversiteit Groningen) and 2MASS.
e = All imaging is from Verheijen (1997, Ph.D. thesis,
Rijksuniversiteit Groningen). Distance is taken as the HST Key
Project distance to the Ursa Major cluster (Sakai et al.
2000ApJ...529..698S 2000ApJ...529..698S), so no heliocentric velocity is listed.
Note (2): Typical uncertainties are ∼5".
Note (3): Flag on Dist, defined as follows:
c = Distance measured from HST observations of Cepheid variable stars,
so no heliocentric velocity is listed.
f = Galaxies that have a triple-valued solution for the Virgo infall
calculation. The chosen solution is the one that is the closest
to the calculated Tully-Fisher distance (given Wr and H-0.5
from Tully 1988, Cat. VII/145).

Note (1): A "i" indicates there were no stars on images to accurately
measure seeing.
Note (2): Flag on mag, defined as follows:
e = Based on a secondary calibration obtained from a short "snapshot"
image taken on a photometric night;
f = For SDSS DR2 images, the zero-point calibration is accurate
to ±2% in r and g-r (Lupton et al. 2001ASPC..238..269L 2001ASPC..238..269L); the sky
variation in our galaxy images causes a further ∼2% uncertainty.
In total, the zero-point calibration is uncertain by ∼4%.
Note (3): Uncertainties in the near-infrared photometry are taken to be ∼4%.
Note (4): Flag on mag1 or mag2, defined as follows:
b = From Ryder et al. (1998MNRAS.293..411R 1998MNRAS.293..411R); not extinction corrected.
c = From the RC3 (Cat. VII/155); not extinction corrected.
d = From Walsh et al. (1997AJ....113.1591W 1997AJ....113.1591W); not extinction corrected.
g = From Lauberts & Valentijn (1989, Cat. VII/115); not extinction
corrected.
h = From Heraudeau & Simien (1996, Cat. J/A+AS/118/111); not extinction
corrected. The error given is the rms error due to uncertainty in the
sky value. The error from the estimated accuracy in the zero-point is
NGC 3726 = 0.1-0.3;
NGC 4062 = ≲0.05;
NGC 4651 = ≲0.05;
NGC 7606 = ≲0.05;

Note (2): n=4 for a de Vaucouleurs r1/4 law, n=1 for an exponential disk.
Note (1): A "a" indicates galaxies with a negligible bulge component. For
these galaxies, we fit an exponential disk, and hence we only list
the central surface brightnesses and scale lengths of the disks.
