Padova-Asiago Supernova Group
The Asiago Supernova Catalogue

Catalog column description
  1. supernova designation. The symbols "?'' denote an unconfirmed SN and "*'' the occurrence of multiple SN discoveries in the same galaxy.
  2. parent galaxy identification. In case a galaxy has different identifications, we adopted the following priority: NGC, IC, MCG (M), UGC, ESO (E), PGC, Leda, others. In some cases specific names are reported, e.g. LMC. Anonymous galaxies are listed with the letter A followed by the coordinates. In a few cases, where the association with a definite parent galaxy was not possible, we have filled the field with INTERGALACTIC.
  3. Right Ascension of the parent galaxy at the 2000.0 epoch.
  4. Declination of the parent galaxy at the 2000.0 epoch.
  5. Right Ascension of the supernova at the 2000.0 epoch.
  6. Declination of the supernova at the 2000.0 epoch.
  7. morphological type of the parent galaxy
  8. morphological type code for the parent galaxy (coding as in RC3).
  9. only for disk-like system, inclination of the polar axis with respect to the line of sight in degrees (0 for face on systems).
  10. position angle of the major axis of the parent galaxy (North Eastwards) in degrees.
  11. heliocentric radial velocity of the parent in km s-1, but for objects with redshift where the z value has been listed.
  12. integrated B magnitude of the parent, mostly from the RC3 or LEDA. In a few cases only photographic magnitudes (prefixed by p) are available.
  13. decimal logarithm of the apparent isophotal diameter, in 0.1 arcmin units.
  14. SN offset from the galaxy nucleus in arcsec, in the E/W direction.
  15. same as above for the N/S direction
  16. if available, supernova magnitude at maximum (photometric band indicated); otherwise discovery magnitude (labelled by *). A magnitude without band means that the observation has not been made in a standard photometric system (e.g. those reported in the discovery announcement as photographic, blue plate, red plate, CCD without filter, and so on).
  17. supernova type, mostly from spectroscopy. In a few cases, marked by *, types have been inferred from the light curve.
  18. if known, epoch of maximum, otherwise * marks date of discovery.
  19. name(s) of discoverer(s). For organized search teams the acronyms are given.
