Abstract:
We present the rotation curves of 967 southern spiral galaxies,
obtained by deprojecting and folding the raw Hα data originally
published by Mathewson, Ford, & Buchhorn (1992ApJS...81..413M 1992ApJS...81..413M). For
900 objects, we also present, in figures and tables, the rotation
curves smoothed on scales corresponding to 5%-20% of the optical size;
of these, 80 meet objective excellence criteria and are suitable for
individual detailed mass modeling, while 820, individually less
compelling mainly because of the moderate statistics and/or limited
extension, are suitable for statistical studies. The remaining 67
curves suffer from severe asymmetries, small statistics, and large
internal scatter that may largely limit their use in galaxy structure
studies. The deprojected folded curves, the smoothed curves, and
various related quantities are available via anonymous ftp at
galileo.sissa.it in the directory /users/ftp/pub/psrot.

Note (1): Set A includes 80 rotation curves that are smooth and symmetric, have
negligible rms internal error, extend to at least the optical radius,
have high and homogeneous radial data coverage.
Set B includes 820 rotation curves of good quality which, however,
have some limitations, such has subsampling, limited extension (i.e.
R(farthest)<3 disk length scales), moderate asymmetries, noncircular
motions, or nonnegligible rms internal error.
Set C includes 67 curves with severe global asymmetries, scanty
sampling, very large rms internal scatter, and conspicuous
noncircular motions.

Note (1): A ')' indicates velocities that come from smooth eyeball
interpolation/extrapolation of the data points, for cases when we have
deemed such a procedure safe.
Note (2): Outermost estimated velocity (for radii≥1.0Ropt) as a representative
measure of the galaxy asymptotic rotation velocity
