Up: Search for correlations between
Subsections
We have searched for supernovae in 3-sigma error-box around
the precise positions of the GRBs. The time correlation has been
ignored due to search for possible recurrences of GRBs.
This is an innovative approach different from studies by other
authors (Kippen et al. 1998
and by Wang & Wheeler 1998).
- there are only 20 precisely localized GRBs by BeppoSAX and
RXTE,
- the typical localization accuracy is 4',
- these objects show non-isotropic distribution over
the sky - only 6 from 20
GRBs have been found on the southern hemisphere.
This distribution is caused by non-isotropic monitoring
of the sky by the BeppoSAX satellite,
- catalogue source: Greiner 1998.
- there are 1443 supernovae detected since 1885,
- non-isotropic distribution due to the galactic extinction and
the observers preferences,
- localization precision better than 1'',
- the supernova SN1998bw is not included,
- catalogue source: CBAT 1998.
