VII/20 Catalogue of HII Regions (Sharpless 1959) ============================================================================ Catalogue of HII Regions Sharpless S.=1959ApJS....4..257S ============================================================================ ADC_Keywords: H II regions; Nebulae Description: The catalogue describes the position, maximum angular diameters, classifications according to form, structure and brightness, and the number of associated stars. The acronym used in the literature to designate objects from this catalogue is Sh 2 (e.g. Sh 2-1 for the first HII region of the catalogue) File Summary: ----------------------------------------------------------------------------- FileName Lrecl Records Explanations ----------------------------------------------------------------------------- ReadMe 80 .
