Notes.

^(a)

The top row shows the FFA16 classification, including their extra-galactic and uncertain candidates.

^(b)

In the middle, the number of overlapping sources of the two catalogs is listed for each sample.

^(c)

The first column shows the MGM classification: protostar (P), faint protostar (FP), red protostar (RP), and disk candidate (D).

^(d)

The first number are all listed HOPS sources in FFA16, and the second number in paranthesis are the sources where SED modeling was applied for sources with sufficient PACS photometry.

^(e)

The last row lists the number of sources that are only in FFA16 and not in MGM.

^(f)

The last column lists the number of sources that are only in MGM but not in FFA16.
