J/A+A/470/787  High energy peaked BL Lacs optical spectros. (Piranomonte+, 2007)

The sedentary survey of extreme high-energy peaked BL Lacs. III. Results from optical spectroscopy. Piranomonte S., Perri M., Giommi P., Landt H., Padovani P. <Astron. Astrophys., 470, 787-809 (2007)> =2007A&A...470..787P

In this paper, the third of the series, we report the results of a dedicated optical spectroscopy campaign that, together with results from other independent optical follow-up programs, led to the spectroscopic identification of all sources in the sample. We carried out a systematic spectroscopic campaign for the observation of all unidentified objects of the sample using the ESO 3.6m, the KPNO 4m, and the TNG optical telescopes. Description: Spectroscopic observations of the Sedentary sources still unidentified and of BL Lacs without redshift were carried out during the period 1999-2003 at the KPNO 4m, at the ESO 3.6m and at the TNG telescopes.
