Query: Measurement of the supermassive black hole masses in two active galactic
  nuclei by the photometric reverberation mapping method   We present the results of long-term photometric monitoring of two active
galactic nuclei, 2MASX J08535955+7700543 (z $\sim$ 0.106) and VII Zw 244 (z
$\sim$ 0.131), being investigated by the reverberation mapping method in
medium-band filters. To estimate the size of the broad line region, we have
analyzed the light curves with the JAVELIN code. The emission line widths have
been measured using the spectroscopic data obtained at the 6-m BTA telescope of
SAO RAS. We give our estimates of the supermassive black hole masses $\lg
(M/M_{\odot})$, $7.398_{-0.171}^{+0.153}$, and $7.049_{-0.075}^{+0.068}$,
respectively
