The intermediate Palomar Transient Factory (ATel #4807)
reports the discovery and classification of the following Type Ia SNe.
Our automated candidate vetting to distinguish a real astrophysical source (1.0) from bogus artifacts (0.0) is powered by three generations of machine learning algorithms:
RB2 (Brink et al. 2013MNRAS.435.1047B), RB4 (Rebbapragada et al. 2015AAS...22543402R) and RB5 (Wozniak et al. 2013AAS...22143105W).
See ATel #7112 for additional details.
The approved classification (and/or subsequent) spectra are made publicly available through WISeREP (Yaron & Gal-Yam 2012).
iPTF15ic and iPTF15iy are presented below to correct for erroneous coordinates specified in ATel #7119.
Name | RA (J2000) | Dec (J2000) | Discovery Date | Mag. | Abs. Mag. | Band | Redshift | Type | Spec. date | Phase | Instrument | Observers/Reducers | Scanner | RB2/RB4/RB5

iPTF15iy | 08:53:33.26 | +61:33:54.5 | 2015-02-11.33 | 20.6 | -19.0 | PTF-g | 0.17 | Ia | 2015-02-13 | +2 days | P200+DBSP | G. Duggan, Y. Cao , P. Bilgi, S. Papadogiannakis / P. Vreeswijk | T. Petrushevska | 0.53/0.40/0.66
[Dates are in UT; the estimated phase, if relevant, is with respect to peak light.]
