| Spectra for over 250,000 Galactic stars of all common spectral types are available with DR6. These Spectra were processed with a pipeline called the 'Spectro Parameter Pipeline' (spp) that computes line indices for a wide range of common features at the radial velocity of the star in question. These outputs are stored in this table, and indexed on the 'specObjID' key index parameter for queries joining to other tables such as specobjall and photoobjall. See the Sample Queries in SkyServer for examples of such queries. |
