Abstract In this paper, accretion disc and synchrotron emission models have been used to analyse simultaneous IR-optical-UV data of the BL Lac object 1727+502. In the following, some of its properties have been discussed. It is shown that the temperature of the disc is about 19, 000°k, the mass of the central black hole isM 8 ≈ 5.4, and the accretion ratio is ≈ 10−3 M ⊙/yr.
