Webb1 aug. 2013 · Data Release 7 (DR7) is the seventh major data release and provides images, imaging catalogs, spectra, and redshifts for download. It is the final data release of … WebbThe SDSS data are stored in vacuum wavelengths. However, most optical astronomers know the wavelengths of transitions as measured at S.T.P., which is how the CRC lists them for any transitions redward of 2000 Angstroms. The IAU standard for conversion from air to vacuum wavelengths is given in Morton (1991, ApJS, 77, 119).
