Statistics of Hotspots in Radio Galaxies
  Based on images from the FIRST survey of the radio sky at 1.4 GHz, the
positions of $\sim$5200 hotspots in $\sim$2870 radio galaxies and quasars were
compiled, and linear sizes and radio luminosities were derived from the hosts
redshifts. For a subsample of $\sim$2100 radio sources with exactly one hotspot
in each of the two opposite lobes, their geometry in terms of asymmetry and
bending was studied. The known (weak) tendency for the brighter lobe (here
hotspot) to lie closer to the host than the fainter one, is confirmed. The
median bending angle between the two arms of radio sources is 4.8$^{\circ}$
with a significant difference in the distribution between the 627 quasar hosts
and the 1501 galaxies.
