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. File Summary:

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
