Gas Kinematics from Halpha line in NGC 4151
Listed in IVOA Registry (Virtual Observatory)
The nucleus spectra of the Seyfert galaxy NGC 4151 obtained in 1988-1991 were analyzed in order to study the profile variability of the Ha line resulting from ionizing continuum flux variations.
Description
At the time of this galaxy monitoring, the response of the integral flux of the Ha line was almost linear and the average profile shape did not change by more than 5%.
