SpecPhotoAllSpectroThis is a pre-computed join between the PhotoObjAll and SpecObjAll tables. There are several criteria used for the join between these two tables, including some tiling and targeting information. Please see the FAQ entry for SpecPhotAll for more information. The photo attributes included are similar to those in PhotoTag. The table also includes certain attributes from Tiles. Many users will want to query the SpecPhoto view, which contains only those objects which are spectroscopically sciencePrimary and photometrically Primary.
