WGAJ0034.4-2133 {alpha}_ACTA_=1.91. Vmag from ESO image
WGAJ0227.5-0847 {alpha}_ACTA_=0.36.
WGAJ0251.9-2051 Optical counterpart 7" off NVSS position. {alpha}_ACTA_=1.70.
WGAJ0305.3-2420 The Ca break for this object is located in noise and its 
WGAJ0305.3-2420 measurement therefore impossible. Based on the relatively large 
WGAJ0305.3-2420 equivalent width of its strongest line, we classify it as a 
WGAJ0305.3-2420 radio galaxy, but note that a classification as a BL Lac cannot 
WGAJ0305.3-2420 be excluded.
WGAJ0322.6-1335 Vmag from ESO image.
WGAJ0421.5+1433 Optical counterpart 9" off NVSS position; NVSS source extended.
WGAJ0421.5+1433 Based on a newly acquired spectrum with a higher SNR than the 
WGAJ0421.5+1433 one published in Paper I (Perlman et al., Cat. <J/AJ/115/1253>) 
WGAJ0421.5+1433 we determine the redshift for this object (z=0.059+/-0.001)
WGAJ0421.5+1433 and reclassify it as a galaxy based on a Ca break value of
WGAJ0421.5+1433 0.51+/-0.14. However, taking the error of the Ca break into 
WGAJ0421.5+1433 account, a classification of this object as a BL Lac cannot be 
WGAJ0421.5+1433 excluded.
WGAJ0513.8+0156 Three NVSS sources; the northermost optical counterpart is in 
WGAJ0513.8+0156 between the two strongest sources, while the southernmost 
WGAJ0513.8+0156 counterpart is 5" off the faintest NVSS source. 
WGAJ0513.8+0156 This is a problematic source. The (uncertain) BL Lac 
WGAJ0513.8+0156 classification of this object given in Paper I (Perlman et al., 
WGAJ0513.8+0156 Cat. <J/AJ/115/1253>) was based on earlier information from the 
WGAJ0513.8+0156 NVSS which at that time listed only one radio source at the 
WGAJ0513.8+0156 position given in Paper I (Perlman et al., Cat. <J/AJ/115/1253>)
WGAJ0513.8+0156 The error circle of the GB6 now in-cludes three NVSS sources. 
WGAJ0513.8+0156 The object published in Paper I (Perlman et al., 
WGAJ0513.8+0156 Cat. <J/AJ/115/1253>) is next to the brightest one at z=0.084. 
WGAJ0513.8+0156 Further observations yielded two other galaxies at redshifts 
WGAJ0513.8+0156 z=0.087 and z=0.092, the former close to the faintest NVSS 
WGAJ0513.8+0156 source, the latter in between the two brightest radio sources. 
WGAJ0513.8+0156 The similar redshifts of the observed galaxies suggest a small 
WGAJ0513.8+0156 group. With the information available, it is currently 
WGAJ0513.8+0156 impossible to say which object is the radio counterpart of the 
WGAJ0513.8+0156 WGA source.
WGAJ0528.5-5820 We refine the redshift of this source to z=0.254+/-0.001; 
WGAJ0528.5-5820 however, the classification as a BL Lac is unaffected. The 
WGAJ0528.5-5820 spectrum of a star close to the DXRBS candidate has been 
WGAJ0528.5-5820 erroneously identified as the optical counterpart in Paper I 
WGAJ0528.5-5820 (Perlman et al., Cat. <J/AJ/115/1253>).
WGAJ0646.8+6807 Optical counterpart 5" off NVSS position. Rmag from WYIN image.
WGAJ0829.5+0858 Vmag from ESO image.
WGAJ0847.2+1133 This object was identified inde-pendently by Cao et al. 
WGAJ0847.2+1133 (1999A&AS..135..243C). We confirm its identification and 
WGAJ0847.2+1133 redshift.
WGAJ0937.1+5008 This object was identified inde-pendently by Henstock et al. 
WGAJ0937.1+5008 (1997MNRAS.290..380H). We confirm its identification and 
WGAJ0937.1+5008 redshift. Our spectrum, however, is significantly bluer and 
WGAJ0937.1+5008 reflects a higher continuum level. As a result, the emission 
WGAJ0937.1+5008 lines in our spectrum are correspondingly weaker.
WGAJ0931.9+5533 Three NVSS sources; optical counterpart in between two of them; 
WGAJ0931.9+5533 possible double-lobed source
WGAJ1026.4+6746 two merged objects in APM: given magnitudes assume a flux ratio 
WGAJ1026.4+6746 of ~2.
WGAJ1056.9-7649 We classify this object as a galaxy, but given the large error 
WGAJ1056.9-7649 on the Ca break we cannot exclude a classification as a BL Lac.
WGAJ1057.6-7724 This object was classified in Paper I (Perlman et al., 
WGAJ1057.6-7724 Cat. <J/AJ/115/1253>) as a BL Lac with an uncertain redshift of 
WGAJ1057.6-7724 z=0.541. A new spectrum obtained in March 1999 at ESO 3.6m 
WGAJ1057.6-7724 yields a reclassification of this source as a radio galaxy with 
WGAJ1057.6-7724 a redshift of z=0.181+/-0.001 and a Ca break value of 
WGAJ1057.6-7724 0.48+/-0.18. Note that the error in the contrast puts this 
WGAJ1057.6-7724 object close to the dividing value of 0.4 adopted by Marcha et 
WGAJ1057.6-7724 al. (1996MNRAS.281..425M) to distinguish radio galaxies from 
WGAJ1057.6-7724 BL Lac objects. Vmag from ESO image.
WGAJ1101.8+6241 Optical counterpart 6" off NVSS.
WGAJ1101.8+6241 This object was identified inde-pendently by Henstock et al. 
WGAJ1101.8+6241 (1997MNRAS.290..380H). We confirm its identification and 
WGAJ1101.8+6241 redshift.
WGAJ1116.1+0828 The redshift for this object given in Table 5 refers to the 
WGAJ1116.1+0828 emission line. The absorption system detected is at 
WGAJ1116.1+0828 z=0.163+/-0.001. Vmag from ESO image.
WGAJ1120.4+5855 The classification of this object as a NLRG is based on the 
WGAJ1120.4+5855 rest-frame equivalent width of 40{AA} fir the strongest emission
WGAJ1120.4+5855 line [O III] {lambda}5007 and is ambiguous without an 
WGAJ1120.4+5855 information on the Ca break strength.
WGAJ1204.2-0710 The claimed redshift for this object is tentative due to the 
WGAJ1204.2-0710 weakness of the identified absorp-tion features.
WGAJ1222.6+2934 A newly acquired spectrum of this source allows a 
WGAJ1222.6+2934 redetermination of the redshift to z=0.787+/-0.001; however, the
WGAJ1222.6+2934 classification as an FSRQ is un-affected.
WGAJ1314.0-3304 {alpha}_ACTA_=0.97.
WGAJ1320.4+0140 The redshift given in Drinkwater et al. (1997, Cat. <VIII/34>) 
WGAJ1320.4+0140 for this object coincides within the errors with the redshift 
WGAJ1320.4+0140 determined from our spectrum. The strongest emission line C III]
WGAJ1320.4+0140 has a rest-frame equivalent width of 9{AA}, therefore we 
WGAJ1320.4+0140 classify this object as a BL Lac.
WGAJ1323.8-3653 We classify this faint object as a BL Lac, based on the absence 
WGAJ1323.8-3653 of strong emission and ab-sorption features. However, we cannot 
WGAJ1323.8-3653 claim this object to be completely featureless, in particular 
WGAJ1323.8-3653 above {lambda}~7,000{AA}, because in that region the lower SNR 
WGAJ1323.8-3653 renders the sky sub-traction problematic.
WGAJ1329.0+5009 This object was identified inde-pendently by Falco, Kochanek, & 
WGAJ1329.0+5009 Munoz (1998ApJ...494...47F). We confirm its identification and 
WGAJ1329.0+5009 redshift.
WGAJ1337.2-1319 {alpha}_ACTA_=0.87.

WGAJ1420.6+0650 This source seems to be partially obcured. We detect a broad 
WGAJ1420.6+0650 H{alpha} emission, but no H{beta} emission is visible.
WGAJ1427.9+3247 Two NVSS sources; optical counterpart in between them; possible
WGAJ1427.9+3247 double-lobed source
WGAJ1457.7-2818 {alpha}_ACTA_=0.72, TEXAS survey double.
WGAJ1506.6-4008 Vmag from ESO image.
WGAJ1539.1-0658 We classify this object as a BL Lac, based on the absence of 
WGAJ1539.1-0658 strong emission and absorption features. However, we cannot 
WGAJ1539.1-0658 claim this object to be com-pletely featureless, in particular 
WGAJ1539.1-0658 above {lambda}~7,000{AA}, because in that region the lower 
WGAJ1539.1-0658 SNR X renders the sky subtraction problematic.
WGAJ1656.6+5321 This object was identified inde-pendently by Falco, Kochanek, & 
WGAJ1656.6+5321 Munoz (1998ApJ...494...47F). We confirm its identification and
