Object Crossid

Upload will let you take a list of objects and upload them temporarily to Skyserver, and find if there is a counterpart to the objects in our database of photometric objects.

Speclist allows you to do dynamic cross identifications of the SDSS spectroscopic objects with a user defined list of (plate, mjd, fiber) values.
