Other spectra
The SDSS often takes repeat spectra of the same object. Each time that
astronomical object is spectroscopically
observed with any of the spectrographs connected to the SDSS telescope, it is assigned a
separate specObjID. We then select the best spectrum and assign it as sciencePrimary.
Information about each spectroscopic observation is stored in the
specObjAll table.
The specObj view
contains only data for spectra assigned as sciencePrimary.
The table below shows all spectra that were measured for this object.
