In current work we continued study of wind parameters of ultraluminous X-ray
sources (ULXs) using model grids of extended atmospheres. We present sets of
models with temperatures from 18000 up to 56000K as a line equivalent widths
(EWs) and their ratios diagrams. The fundamental wind parameters for some
spectrally studied ULXs were estimated using EW diagrams. Also, influence of
the wind velocity law on the equivalent widths of observed emission lines was
investigated. This study was funded by RFBR according to the researchproject
18-32-20214.
