Abstract:
    We present the final data release of the high sensitivity
    {lambda}21-cm neutral hydrogen survey of the sky south of
    {delta}<=-25{deg}. A total of 50980 positions lying on a
    galactic coordinate grid with points spaced by
        ({Delta}l, {Delta}b)=(0.5{deg}/cosb, 0.5{deg})
    were observed with the 30m dish of the Instituto Argentino de
    Radioastronomica (IAR). The angular resolution of the survey is
    HPBW=0.5{deg} and the velocity coverage spans the interval -450km/s
    to +400km/s (LSR). The velocity resolution is 1.27km/s and the final
    rms noise of the entire database is 0.07K. The data are corrected for
    stray radiation and converted to brightness temperatures.

Description:
    All 50980 observed profiles have been combined to a single fits data
    cube, iar_1008.fits. It contains the Argentine survey corrected for
    baseline and stray radiation as used for the LAB combined database, in
    the original observed velocity resolution.
