Abstract:
We present the final data release of the high sensitivity
λ21-cm neutral hydrogen survey of the sky south of
δ≤-25°. A total of 50980 positions lying on a
galactic coordinate grid with points spaced by
(Δl, Δb)=(0.5°/cosb, 0.5°)
were observed with the 30m dish of the Instituto Argentino de
Radioastronomica (IAR). The angular resolution of the survey is
HPBW=0.5° 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.
