... For example, as pointed out by Perlman et al. (1996b), the lack of a Ca II H & K break strength criterion in the 1 Jy, S4 and S5 samples of BL Lacs, has caused numerous objects to be misclassified as radio galaxies instead of BL Lacs (see also March? Browne 1995, 1996). ... While one may argue that some of these objects fall in the expanded region of the (H & K break strength, equivalent width) diagram that March? et al. (1996) allot to the BL Lacs, several, for example 1 Jy 1308+326, do not. ...
