Notes.
Each redshift inferred by SNID carries a rlap parameter. This is a reliability metric that reflects the strength of the spectral cross correlation and the extent of wavelength overlap between the observed spectrum and the matched template. Higher rlap values correspond to better spectral matches, and values above ≈5 are generally considered significant for classification.
Terreran (2021) reported a redshift of z = 0.035 to the Transient Name Server along with their classification spectrum.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
