Notes.

^(a)

Test using only sources with z < 1 in the extended samples.

^(b)

Test with the extended/point-like splitting using only the SDSS classification.

^(c)

Test using only optical data from the common filters between the SDSS and Pan-STARRS samples (g, r, i, z).

^(d)

The numbers inside the parenthesis refers to the number of filters in the SDSS-c and Pan-STARRS-c samples.
