Abstract:
This paper presents 828 new 21-cm neutral hydrogen line measurements
carried out with the FORT receiver of the meridian transit Nancay
radio telescope (NRT) in the years 2000-2007. This observational
program was part of a larger project aiming at collecting an
exhaustive and magnitude-complete HI extragalactic catalog for
Tully-Fisher applications. Through five massive data releases, the
KLUN series has collected an homogeneous sample of 4876 HI-spectra of
spiral galaxies, complete down to a flux of 5Jy.km/s and with
declination δ>-40^°. We publish here the last release of the
KLUN HI observational program, corresponding to the faint end of the
survey, with HI masses ranging from 5x108 to 5x1010 solar masses.
The size of this final sample is comparable to the catalogs based on
the Arecibo and Parkes radio telescope campaigns, and it allows
general HI-mass distribution studies from a set of homogeneous radio
measurements.
Description:
HI data for a catalog of 828 late type galaxies
Table 2 contains the measured HI parameters : for each galaxy
equatorial coordinates, radial velocity, HI line width,
HI flux and signal to noise ratio are given.
Comments associated to each galaxy and complementary informations about
the radio observation are given in Table 3.
HI spectra are provided in ASCII format as 828 "pgcname.dat" files.

Global notes:
Note (G1): Quality code as follows:
A = high quality spectrum, high signal to noise and well defined HI profile
B = good signal to noise ratio, well defined edges of the line,
width OK for TF applications
C = low signal to noise, noisy or asymmetrical profile, possible HI confusion
but well defined systemic radial velocity
D = low signal to noise, noisy profile at the limit of detection. Rejected
E = not detected
Note (G2): Flag as follows:
c = confirmed HI confusion
? = suspected
