Beginning of ReadMe : VIII/75 HI survey of the sky DE<+25deg (Bajaja+, 2005) ================================================================================ A high sensitivity HI survey of the sky at delta<+25deg. Final data release. Bajaja E., Arnal E.M., Larrarte J.J., Morras R., Poeppel W.G.L., Kalberta P.M.W. <Astron. Astrophys. 440, 767 (2005)> =2005A&A...440..767B ================================================================================ ADC_Keywords: Surveys ; H I data ; Radio lines Keywords: surveys - ISM: general - Galaxy: general - radio lines: ISM - ISM: clouds Abstract: We present the final data release of the high sensitivity lambda21-cm neutral hydrogen survey of the sky south of delta<=-25deg. A total of 50980 positions lying on a galactic coordinate grid with points spaced by (Deltal, Deltab)=(0.5deg/cosb, 0.5deg) were observed with the 30m dish of the Instituto Argentino de Radioastronomica (IAR). The angular resolution of the survey is HPBW=0.5deg 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.
