Table information for 'lamost5.data'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description:

This services provides 1D spectra from DR5 of LAMOST (Large Sky Area Multi-Object Fiber Spectroscopic Telescope) through SSAP and Obscore; data is served both in VO-standard SDM and, via datalink, the original SDSS-inspired FITS described in http://dr5.lamost.org/doc/data-production-description .

For a list of all services and tables belonging to this table's resource, see Information on resource 'LAMOST DR5 survey spectra'
