Abstract

We have investigated the difference between distributions of intrinsic opening angle for the parsec-scale jets of 44 quasars and those of 12 BL Lacs. We used 15.4 GHz VLBA observations of the 56 sources from the 2 cm VLBA MOJAVE program to determine their apparent jet opening angles by analyzing transverse jet profiles from the data in the image plane. We have found that BL Lacs have on-average wider intrinsic opening angles than those in quasars, while the corresponding distributions of the apparent opening angle are found to be similar.
