Query: SDSS photometry of Asteroids in Cometary Orbits   Aiming at exploring the relationship between asteroids in cometary orbits and
other minor body populations from the observational point of view, I explore
the large photometric database of the Sloan Digital Sky Survey - Moving Objects
Catalog.
  The sample of interest was carefully selected analyzing colors and orbital
properties within the data in the catalog. I computed the spectral slope for
each object and compared with published spectroscopic results of other
Asteroids in Cometary Orbits, as well as with other populations of asteroids in
the outer region of the Main belt and Trojans.
  Using this extended database I find that Asteroids in Cometary Orbits with
Tisserand parameter below 2.9, and especially below 2.8, are most likely of
primitive origin. The population of objects with Tisserand parameter larger
than 2.9 is a mixture of populations ranging from the inner to the outer Main
belt.
