| Abstract: |
The data reduction for an all-sky galactic 21-cm line survey, merging the Instituto Argentino de Radioastronomia (IAR) and the Leiden-/Dwingeloo survey (LDS) databases is approaching its final phase.
For the first time a sensitive homogeneous all-sky survey with an angular resolution of 0.5 degree and a velocity resolution of ∼ 1 kms−1 becomes available. All data of this all sky survey have been corrected for stray-radiation to an accuracy which is on average comparable to the stray radiation free Bell Labs Survey. This database allows to study details of the Milky Way structure at high as well as at low galactic latitudes. In future it may serve also as a reference for surveys with higher spatial resolution. |
