A high sensitivity HI survey of the sky at delta less than or equal to -25 degree : Final data release

We present the final data release of the high sensitivity lambda 21-cm neutral hydrogen survey of the sky south of delta less than or equal to -25 degree . A total of 50 980 positions lying on a galactic coordinate grid with points spaced by ( Delta l, Delta b) = (0. degree 5/cos b, 0. degree 5) wer...

Summary:We present the final data release of the high sensitivity lambda 21-cm neutral hydrogen survey of the sky south of delta less than or equal to -25 degree . A total of 50 980 positions lying on a galactic coordinate grid with points spaced by ( Delta l, Delta b) = (0. degree 5/cos b, 0. degree 5) were observed with the 30-m dish of the Instituto Argentino de Radioastronomia (IAR). The angular resolution of the survey is HPBW = 0. degree 5 and the velocity coverage spans the interval -450 km s super(-1) to +400 km s super(-1) (LSR). The velocity resolution is 1.27 km s super(-1) 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.
