J/A+A/538/A120      A unified supernova catalogue            (Lennarz+, 2012)

A unified supernova catalogue. Lennarz D., Altmann D., Wiebusch C. <Astron. Astrophys. 538, A120 (2012)> =2012A&A...538A.120L
ADC_Keywords: Surveys ; Supernovae Keywords: supernovae: general - catalogs Description: A supernova catalogue containing data for 5526 extragalactic supernovae that were discovered up to 2010 December 31. It combines several catalogues that are currently available online in a consistent and traceable way. During the comparison of the catalogues inconsistent entries were identified and resolved where possible. Remaining inconsistencies are marked transparently and can be easily identified. Thus it is possible to select a high-quality sample in a most simple way. Where available, redshift-based distance estimates to the supernovae were replaced by journal-refereed distances.

Note (1): Code on Supernova designation as follows: 1 = SN flagged uncertain or not listed in the SSC (Sternberg Cat. II/256) 2 = SN flagged uncertain or not listed in the ASC (Asiago Cat. B/sn) 3 = SN flagged uncertain or neither listed in the ASC or SSC Note (2): The SN host galaxy is crucial because the properties of the host galaxy are important for statistical studies and it can be used to obtain a redshift-independent distance estimate. Therefore, the host galaxies were carefully selected. The provided galaxy identification is the HyperLeda principal identifier if the host galaxy is known. A host galaxy in brackets means that this host galaxy is only given in the SSC. Presumably, the SSC uses the closest known galaxy to the SN position as host, but this information should be treated with caution (e.g. the real SN host galaxy may not have been catalogued). Note (3): * means that for this galaxy the parameter "objtype" in HyperLeda is different from "G" for galaxy or "Q" for a quasi-stellar object (QSOs). Currently, all these objects are marked as an "extended source of unknown/uncertain nature". Note (4): Code on Supernova position as follows: 1 = SN positions are inconsistent between catalogues by more than 5" 2 = SN position was obtained directly from a specific publication and was manually inserted into the catalogue 3 = SN position was calculated from the host galaxy position and the SN offset Note (5): Code on Supernova offset from host galaxy as follows: 1 = SN offset was obtained directly from a specific publication and was manually inserted into the catalogue 2 = SN offset comes from one catalogue only 3 = SN offsets are inconsistent between catalogues by more than 5". Note (6): Code on Supernova type as follows: 1 = type is flagged uncertain in at least one catalogue 2 = type information comes from one catalogue only 3 = at least one catalogue does not list the subtype (e.g. one catalogue I, the other two Ia) Note (7): Code on Discovery date as follows: 1 = value comes from less than three catalogues 2 = difference ≤10 days 3 = 1+2 4 = difference >10 days Note (8): Code on Discovery magnitude as follows: 1 = value comes from less than three catalogues 2 = difference ≤0.5mag 3 = 1+2 4 = difference > 0.5mag Note (9): Code on Maximum date as follows: 1 = value comes from one catalogue only 2 = difference ≤5 days 3 = difference > 5 days Note (10): Code on Magnitude at maximum as follows: 1 = value comes from one catalogue only 2 = difference ≤0.5mag 3 = difference > 0.5mag Note (11): Code on Host galaxy position: * = host galaxy position was modified manually Note (12): Code on Host galaxy redshift as follows: 1 = ASC deviates by more than 10% from HyperLeda value 2 = SSC deviates by more than 10% from HyperLeda value 3 = ASC and SSC deviate by more than 10% from HyperLeda value 4 = SSC within 10% of ASC value 5 = SSC outside 10% of ASC value 6 = value given only in the ASC 7 = value given only in the SSC
