J/A+AS/25/25        HII regions of the Northern Milky Way (Dubout-Crillon+ 1976)

HII regions of the Northern Milky Way: medium large field photographic atlas and catalogue. Dubout-Crillon R. <Astron. Astrophys. Suppl. Ser., 25, 25-54 (1976)> =1976A&AS...25...25D
ADC_Keywords: H II regions ; Photometry, H-alpha Keywords: galactic HII regions ; medium-large-field ; interference filter Abstract: Nineteen Hα photographs and a catalogue of HII regions in the northern Milky Way are presented. This atlas reveals 85 new regions of faint emission. Description: The photographs were made at the Observatoire de Haute-Provence at the end of 1969, throughout 1970, and then again in 1972. A 5cm refractor was used with a very selective interference filter (Δλ=10Å) centered on Hα, and a focal reducer took the f/5 beam down to f/1.25. Exposures were made using flashed 103-aE plates. The catalogue includes also the HII regions discovered by Sivan 1974 (Compt. Rend. Acad. Sci. Paris 278, 127; 1974A&AS...16..163S). File Summary:
