Abstract:
This is the first paper of a series in which we present new
measurements of the observed rates of supernovae (SNe) in the local
Universe, determined from the Lick Observatory Supernova Search. We
have obtained 2.3 million observations of 14 882 sample galaxies over
an interval of 11 years (1998 March to 2008 December). We considered
1036 SNe detected in our sample and used an optimal subsample of 726
SNe (274 Type Ia SNe, 116 Type Ibc SNe and Type II 324 SNe) to
determine our SN rates. This is the largest and most homogeneous set
of nearby SNe ever assembled for this purpose, and ours is the first
local SN rate analysis based on CCD imaging and modern
image-subtraction techniques. In this paper, we lay the foundation of
the study.
Description:
The requirement to have the Hubble type and photometry results in
further cuts to our galaxy sample, and our final sample has 14882
galaxies (hereinafter the "full" galaxy sample). All of the
galaxies in this sample have Hubble-type information, 98.6 per cent
have B-band photometry and 91.8 per cent have K-band photometry.

Global notes:
Note (G1): Sub-samples defined as follows:
o = Optimal subsample: small early-type galaxies and highly inclined
spiral galaxies (i>75°) are excluded. It represents the galaxy
sample used for the rate calculations.

are excluded.
f = includes all of the galaxies within 60Mpc in the "nosmall" galaxy

LF study in Paper II (Li et al., Cat. J/MNRAS/412/1441).
Note (G2): Sources as follows:
LEDA = HyperLeda Database (http://leda.univ-lyon1.fr)
NED = NASA/IPAC Extragalactic Database (http://nedwww.ipac.caltech.edu)
SIMD = Simbad database (http://simbad.u-strasbg.fr/simbad/)
TURA = (unspecified location)
Note (G3): Hubble type as:
1 = E; 2 = S0; 3 = Sa; 4 = Sb; 5 = Sbc; 6 = Sc; 7 = Scd; 8 = Irr
