J/MNRAS/277/1477 A catalogue of BL Lacertae objects (Padovani+ 1995)
================================================================================
A sample-oriented catalogue of BL Lacertae objects

ADC_Keywords: BL Lac objects ; X-ray sources ; Radio sources
Description:
We present a catalogue of 233 BL Lacertae objects compiled through an
extensive bibliographic search updated to mid-1995. A large fraction
of the sources listed in the catalogue belongs to well-defined samples
and can be used for statistical purposes. A smaller fraction consists
of miscellaneous (but confirmed) BL Lacs and of objects classified as
BL Lac candidates. We discuss the selection criteria of the different
samples, report the discovery of two previously unnoticed BL Lacs in
the Palomar-Green survey, and comment on the possible association of
some of the still unidentified high galactic latitude gamma-ray
(EGRET, see Thompson et al., =1995ApJS..101..259T) sources with BL
Lacs. Some statistical properties of the catalogue are also briefly
discussed.

Note (1):
a - Derived from the B magnitude assuming B-V = 0.6, the mean value
for BL Lacs
b - radio flux at 8.4 GHz
c - detected only during phase 2 of the EGRET observations and therefore
not included in the phase 1 EGRET catalogue of Fichtel et al.
(1994ApJS...94..551F)
d - from Murphy, Browne & Perley (1993MNRAS.264..298M);
Perlman et al. (1995b, ApJS, in press) give no redshift,
so this value might be uncertain
e - derived from the mean B magnitude using the observed value of B-V
