VizieR Online Data Catalog: Bgri light curves of PTF11kmb and PTF12bho (Lunnan+, 2017)

The objects PTF11kmb and PTF12bho were found as part of the Palomar Transient Factory (PTF). PTF11kmb was discovered in data taken with the 48 inch Samuel Oschin Telescope at Palomar Observatory (P48) on 2011 August 16.25 at a magnitude r=19.8mag. A spectrum was taken with the Low Resolution Imaging Spectrometer (LRIS) on the 10m Keck I telescope on 2011 August 28, showing SN features consistent with a SN Ib at a redshift z=0.017. The source PTF12bho was discovered in P48 data on 2012 February 25.25 at a magnitude of r=20.52mag. A spectrum taken with LRIS on 2012 March 15 yields z=0.023 based on the SN features.

We obtained R- and g-band photometry of PTF11kmb and PTF12bho with the P48 CFH12K camera. Additional follow-up photometry was conducted with the automated 60-inch telescope at Palomar (P60) in the Bgri bands, and with the Las Cumbres Observatory (LCO) Faulkes Telescope North in gri.

PTF12bho was also observed with the Swift Ultra-Violet/Optical Telescope (UVOT) and the Swift X-ray telescope (XRT) on 2012 March 17.8 for 3ks. We obtained a sequence of spectra for both PTF11kmb and PTF12bho using LRIS on Keck I, the DEep Imaging Multi-Object Spectrograph (DEIMOS) on the 10m Keck II telescope, and the Double Spectrograph (DPSP) on the 200-inch Hale telescope at Palomar Observatory (P200) spanning 2011 Aug 28.5 to 2014 Jul 2.5. We obtained deep imaging of the fields of PTF11kmb using WFC3/UVIS on the Hubble Space Telescope (HST) through program GO-13864 (PI Kasliwal) in 2015 Jul 12. This program also covered the field of SN 2005E (2014 Dec 10).
