Abstract:
The potential-density phase-shift method (Zhang et al.,
2007AJ....133.2584Z 2007AJ....133.2584Z) is an effective new tool for investigating the
structure and evolution of galaxies. In this paper, we apply the
method to 153 galaxies in the Ohio State University Bright Galaxy
Survey (OSUBGS) to study the general relationship between pattern
corotation radii and the morphology of spiral galaxies. The analysis
is based on near-infrared H-band images that have been deprojected and
decomposed assuming a spherical bulge.
Description:
In this paper, we apply the phase-shift method to a much larger sample
of galaxies than in Paper I: the Ohio State University Bright Spiral
Galaxy Survey (OSUBSGS; Eskridge et al. 2002, Cat. J/ApJS/143/73).
This survey includes all RC3 (de Vaucouleurs et al., 1991, Cat.
VII/155) galaxies having a type in the range S0/a to Sm, total blue
magnitude BT≤12.0, blue light isophotal diameter D25≤6.5', and
declination in the range -80<δ<+50{dd}.

Note (1): The "b" flag indicates a CR5 value of 134.0" and f_CR5 equal 3.
Note (2): Radii of inferred corotations from positive-to-negative
potential-density phase-shift crossings.
Note (3): Flags as follows:
* = Judgment of the bar corotation radius.
b = Alternative interpretation of the bar corotation radius.
Note (4): Number is given in these columns only if the phase-shift crossing
is noisy. Then, the value is a standard deviation about an average
crossing radius.
Note (5): Indicates how significant we think a crossing is. Code 3
crossings are considered more reliable than code 1 crossings.
