VizieR Online Data Catalog: Follow-up Opt. and NIR obs. of the SNIa SN2015bp (Wyatt+, 2021)

SN 2015bp was discovered on 2015 March 16, 11:45:36 (JD=2457097.99) by the Catalina Real-time Transient Survey (CRTS; Drake+ 2009, J/ApJ/696/870).

Following discovery, observations were initiated by the Carnegie Supernova Project II (CSP-II; Phillips+ 2019PASP..131a4001P and Hsiao+ 2019, J/PASP/131/A4002), and optical photometric observations began on 2015 March 19 using the Henrietta Swope 1m telescope at Las Campanas Observatory in Chile. The Swope observations continued until 2015 August 15, obtaining 45 epochs in the CSP-II optical Johnson (BV) and Sloan (ugri) filters. Once SN 2015bp had sufficiently faded in March 2016, host-galaxy reference images were obtained for template subtraction.

Retrocam on the du Pont 2.5m telescope located at Las Campanas Observatory was also used to obtain 11 epochs of NIR photometric data in the YJH filters starting on 2015-March-28 and ending on 2015-May-30. See Section 2.1.

Optical spectroscopic observations began on 2013 March 20 and were made with the low-resolution EFOSC2 spectrograph on the 3.6m New Technology Telescope (NTT), the Wide-Field Reimaging CCD Camera (WFCCD) on the du Pont 100 inch telescope, the Deep Imaging Multi-Object Spectrograph (DEIMOS) on the Keck II 10m telescope, and the Andalucia Faint Object Spectrograph and Camera (ALFOSC) on the Nordic Optical Telescope (NOT). We also include some already published spectra from Srivastav+ (2017MNRAS.466.2436S), which help fill in the post-maximum evolution. The EFOSC2 data were taken as part of the Public ESO Spectroscopic Survey of Transient Objects (PESSTO) project (Smartt+ 2015, J/A+A/579/A40), and the reduced spectra were downloaded directly from the ESO archive.

NIR spectroscopic observations began on 2015 March 21 using the Son of ISAAC (SOFI) instrument on the NTT, the Folded-port Infrared Echellette (FIRE) spectrograph on the Magellan Baade telescope, the Gemini Near Infrared Spectrograph (GNIRS) on the Gemini North Telescope, SpeX on the NASA Infrared Telescope Facility (IRTF), and the Flamingos2 spectrograph (F2) on the Gemini South Telescope. The SOFI data were taken during the PESSTO survey, and we downloaded the reduced spectra directly from the ESO archive.
