DR1 includes two types of data: optical spectra (flux- and wavelength-calibrated, sky-subtracted), and catalog data, which includes both parameters measure from spectra, such as redshifts and signal to noise ratios, and parameters inherited from input catalogs. You should keep in mind that LAMOST is a spectral survey telescope, and the parameters related to photometry, which you get here, all come from other surveys. http://dr1.lamost.org Survey Research related-to 2 http://dr1.lamost.org/voservice/ssap? query survey spectralExtraction ICRS 10.0004738 40.9952444 0.2 2 http://dr1.lamost.org/search
