VizieR Online Data Catalog: UV/optical/NIR photometry for Type Ibn SNe (Pastorello+, 2015)

We started our optical and near-infrared (NIR) observational campaigns soon after the classification announcements of the two SNe, using the instruments available to our collaboration (see Tables A3 and A4). Additional photometry with small-size telescopes was kindly provided by amateur astronomers. Both SNe 2010al and 2011hw were visible for only 60-70 d after their discoveries, then they disappeared behind the Sun. We tried to recover SN 2010al at very late phases, but it was only visible in NIR observations obtained with the 8.4-m Large Binocular Telescope (Mt. Graham, Arizona; USA) equipped with Lucifer. Additional space observations of SNe 2010al and 2011hw in the ultra-violet (UV) and optical bands were obtained with the Swift satellite and its Ultraviolet/Optical Telescope (UVOT). These data were useful to constrain the large energy contribution of the UV domain in the early phases of the evolution of the two SNe.
