Abstract:In the Spring of 2011 we carried out a 2.5 month reverberation mapping campaign using the 3m Shane telescope at Lick Observatory, monitoring 15 low-redshift Seyfert 1 galaxies. This paper describes the observations, reductions and measurements, and data products from the spectroscopic campaign. The reduced spectra were fitted with a multicomponent model in order to isolate the contributions of various continuum and emission-line components. We present light curves of broad emission lines and the active galactic nucleus (AGN) continuum, and measurements of the broad H{beta} line widths in mean and rms spectra. For the most highly variable AGNs we also measured broad H{beta} line widths and velocity centroids from the nightly spectra.

This project was allocated 69 nights at the Lick 3m Shane telescope,
distributed between 2011 March 27 and June 13. Observations were
conducted using the Kast double spectrograph (3440-5515{AA} on the
blue side and 5410-8200{AA} on the red side).
In order to extend our light curves for two AGNs, we also requested
additional observations from other observers using the Kast
spectrograph: Mrk 50 from 2011 January through March, and Zw 229-015
in June and July. For Zw 229-015, three additional observations were
taken 20-23 days after the end of our main campaign. See section 3.
