a: RX J0223.4 (z=0.163) was detected in pointing rp800016n00, the central
 a  target of which was a wide angle radio (WAR) source. The cluster hosting
 a  this WAR source has a redshift of z=0.41 (Nichol et al.,
 a  1994MNRAS.267..771N). The redshift separation of the two clusters is
 a  {delta}z~0.247.
 b: RX J0318.5 (z=0.37) was detected in wp800555n00 which was pointed,
 b  accidentally, ~40{deg} away in declination away from the listed target,
 b  A3112, which lies at 03 17 56-44 14 17 (Ebeling et al.,
 b  1996MNRAS.281..799E).
 c: RX J0321.9 (A3120, z=0.0696) was detected in wp800371n00, the central target
 c  of which was a Couch et al. (1991MNRAS.249..606C) cluster at z=0.49. The
 c  redshift separation of the two clusters is {delta}z=0.42.
 d: RX J0454.3 (z=0.26) was detected in rp800229n00, the central target of which
 d  was cluster MS0451.6 (z=0.55; Gioia & Luppino, 1994ApJS...94..583G). The
 d  redshift separation of the two clusters is {delta}z=0.29.
 e: RX J1024.3 (A981, z=0.201) was detected in wp800641, the central target of
 e  which was cluster A998 (z=0.202; Huchra et al., 1990, Cat. <J/ApJ/365/66>).
 e  The redshift separation of the two clusters is {delta}z=0.001.
 f: RX J1259.7 (z=0.076) was detected in rp800384n00, the central target of
 f  which was cluster A3537 (cz=5007 km/s; Abell et al., 1989, Cat. <VII/110>).
 f  The redshift separation of the two clusters is {delta}z=0.059.
 g: RX J1334.3 (z=0.62) was detected in rp800047, the central target of which
 g  was cluster A1758 (z=0.2792; Allen et al., 1992MNRAS.259...67A). The
 g  redshift separation of the two clusters is {delta}z= 0.34.
 h: RX J1416.4 (z=0.138) was detected in rp800401a01, the central target of
 h  which was galaxy 4C23.37 (cz=154 km/s; De Vaucouleurs et al., 1991, Cat.
 h  <VII/155>). The redshift separation of the two clusters is {delta}z=0.137.
 i: RX J1541.1 (z=0.245) was detected in rp800511n00, the central target of
 i  which was A2125 (z=0.2465; Struble & Rood, 1987ApJS...63..543S). The
 i  redshift separation of the two clusters is {delta}z=0.0015.
