a Columns (1) and (2) give the name and redshift of the BL Lac;
Cols. 3 and 4: the absolute magnitude of the host galaxy in the H-band
(this work) and R-band (literature values), respectively;
Col. 5: the references for Col. 4; Col. 6: the R-H colour of the host galaxy
computed from Cols. 3 and 4; and Col. 7: the R-H colour gradient of
the host.
