The goal of this work is to obtain the bolometric light curves of superluminous supernovae (SLSN) using data from the Open Supernova Catalog (OSC) and vector Gaussian processes (GP). The catalog contains photometric observations (light curves) of supernovae in different passbands. The multicolor light curves presented in the OSC are inhomogeneous in time. Therefore, to obtain a quasi-bolometric light curve, the existing light curves must be approximated. In this work, it is achieved by using the vector GP. To obtain the bolometric light curves we used an assumption that at any moment in time the spectrum of a supernova can be described by a black body spectrum with a certain temperature and radius. Using the approximated multicolor light curves, we can fairly accurately estimate the parameters of a black body at a given time and calculate the bolometric light curve. For a sample of SLSN from OSC, we constructed the bolometric light curves and referred them to the same rest-frame. This allows to compare the light curves and to extract information about the progenitor.
