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)
