Abstract:
We present new long-slit Hα spectroscopy for 403 non-interacting
spiral galaxies, obtained at the Palomar Observatory 5m Hale
telescope, which is used to derive well-sampled optical rotation
curves. Because many of the galaxies show optical emission features
that are significantly extended along the spectrograph slit, a
technique was devised to separate and subtract the night sky lines
from the galaxy emission. We exploit a functional fit to the rotation
curve to identify its center of symmetry; this method minimizes the
asymmetry in the final, folded rotation curve. We derive rotational
widths using both velocity histograms and the Polyex model fit. The
final rotational width is measured at a radius containing 83% of the
total light as derived from I-band images.
Description:
The optical long-slit spectroscopy presented in this work was obtained
at the Palomar Observatory 5m Hale telescope. A total of 20 nights
(19 of which had weather conditions adequate for spectroscopy) were
allocated over the course of five observing runs.

Note (1): Referred to as the Arecibo General Catalog (AGC).
If a galaxy is also listed in the UGC catalog (Nilson 1973,
Cat. VII/26), its UGC and AGC codes are identical.
Note (2): NGC or IC designation, or other name, typically from the CGCG
(Zwicky et al. 1961-68, Cat. VII/190) or MCG (Vorontsov-Velyaminov &
Arhipova 1968, Cat. VII/62) catalogs. CGCG numbers are listed in the
form: field number-ordinal number within the field; MCG designations
are abbreviated to eight characters.
Note (3): Coordinates have been obtained from the Digitized Sky Survey
catalog and are accurate to within 2 arcseconds.
Note (4): Code 1 corresponds to Sa, code 3 to Sb, code 5 to Sc, etc.
A "B" following the type code indicates the presence of
an identifiable bar.
Note (5): Polyex fit flag, defined as follows:
1 = good or acceptable fit;
0 = poor fit.
Note (6): Where V80=(V10+V90)/2, V10 and V90 being the 10th and
90th percentile points of the RC velocity histogram.
Note (7): Where W80=V90-V10, V10 and V90 being the 10th and 90th percentile
points of the RC velocity histogram.
