A spectral atlas for these stars is prepared in the wavelength interval of 3920 to 6720 \\AA.", "revisions": [ { "version": "v1", "updated": "2015-02-05T07:19:19.000Z" } ], "analyses": { "keywords": [ "a-type supergiants", "spectral atlas", "echelle spectrograph nes", "bta telescope", "peculiar supergiant" ], "note": { "typesetting": "TeX", "pages": 56, "language": "en", "license": "arXiv", "status": "editable" } } }
