Catalog of One-side Head-Tail Galaxies in the FIRST Survey
  One-side head-tail (OHT) galaxies are radio galaxies with a peculiar shape.
They usually appear in galaxy clusters, but they have never been cataloged
systematically. We design an automatic procedure to search for them in the
Faint Images of the Radio Sky at Twenty-Centimeters source catalog and compile
a sample with 115 HT candidates. After cross-checking with the Sloan Digital
Sky Survey photometric data and catalogs of galaxy clusters, we find that 69 of
them are possible OHT galaxies. Most of them are close to the center of galaxy
clusters. The lengths of their tails do not correlate with the projection
distance to the center of the nearest galaxy clusters, but show weak
anticorrelation with the cluster richness, and are inversely proportional to
the radial velocity differences between clusters and host galaxies. Our catalog
provides a unique sample to study this special type of radio galaxies.
