The UV-excess survey of the northern galactic plane
(2009)
The UV-Excess survey of the northern Galactic plane images a 10°× 185° wide band, centred on the Galactic equator using the 2.5-m Isaac Newton Telescope in four bands ( U, g, r, He i 5875) down to ∼21–22 mag ( ~20 in He i ...
High spatial resolution Galactic 3D extinction mapping with IPHAS
(2009)
We present an algorithm (MEAD, for ‘Mapping Extinction Against Distance’) which will determine intrinsic (r′−i′) colour, extinction, and distance for early-A to K4 stars extracted from the IPHAS r′/i′/Hα photometric data ...
