A high sensitivity HI survey of the sky at δ ≤ -25° : Final data release

We present the final data release of the high sensitivity λ 21-cm neutral hydrogen survey of the sky south of δ ≤ -25°. A total of 50 980 positions lying on a galactic coordinate grid with points spaced by (Δl, Δb) = (0°.5/cos b, 0°.5) were observed with the 30-m dish of the Instituto Argentino de R...

description We present the final data release of the high sensitivity λ 21-cm neutral hydrogen survey of the sky south of δ ≤ -25°. A total of 50 980 positions lying on a galactic coordinate grid with points spaced by (Δl, Δb) = (0°.5/cos b, 0°.5) were observed with the 30-m dish of the Instituto Argentino de Radioastronomía (IAR). The angular resolution of the survey is HPBW = 0°.5 and the velocity coverage spans the interval -450 km s<SUP>-1</SUP> to +400 km s<SUP>-1</SUP> (LSR). The velocity resolution is 1.27 km s<SUP>-1</SUP> and the final rms noise of the entire database is 0.07 K. The data are corrected for stray radiation and converted to brightness temperatures.
