Checking point sources in 2MASS All-Sky Point Source Catalog

[Cosmolog]

I want to check my probable point sources by this link http://vizier.u-strasbg.fr/viz-bin/VizieR?-source=II/246.

for example I input the coordinates of M31(in galactic or ecuatorial system) and the search engine doesn't give any result, no object found. But M31certainly is in 2MASS catalog

 

How should I use this search engine ?

 

Thank You in advance.
