ROTATION CURVES OF 967 SPIRAL GALAXIES

We present the rotation curves of 967 southern spiral galaxies, obtain ed by deprojecting and folding the raw Ha data originally published by Mathewson, Ford, & Buchhorn (1992). For 900 objects, we also present, in figures and tables, the rotation curves smoothed on scales corresp onding to 5%-20% of the optical size; ofthese, 80 meet objective excel lence criteria and are suitable for individual detailed mass modeling, while 820, individually less compelling mainly because of the moderat e statistics and/or limited extension, are suitable for statistical st udies. The remaining 67 curves suffer from severe asymmetries, small s tatistics, and large internal scatter that may largely limit their use in galaxy structure studies. The deprojected folded curves, the smoot hed curves, and various related quantities are available via anonymous ftp at galileo.sissa.it in the directory /users/ftp/pub/psrot.
