TITLE: GCN CIRCULAR NUMBER: 18371 SUBJECT: LIGO/Virgo G184098: Update to LT Spectroscopy of PS15ccx DATE: 15/09/27 16:15:17 GMT FROM: Iain Steele at Liverpool/JMU I.A Steele, C.M. Copperwheat, A.S. Piascik (Liverpool JMU) report on behalf of the larger ARI-LJMU collaboration In further analysis of the LT spectrum reported in GCN 18370 of PS15ccx we have now succeeded in obtaining a classification of the spectrum using SNID by truncating the wavelength range to between 4500 and 7500 Angstroms to remove the regions of poorest signal to noise ratio. SNID reports a 96% probability that the transient is a Supernova Type Ia at age 15-23 days post maximum with z~0.097. ________________________________ Important Notice: the information in this email and any attachments is for the sole use of the intended recipient(s).
