identified stars

After some fiddling in Aladin version 10, with the NED catalogue, I was able to get the identifiers for the stars around gamma Her.

2MASS J16215298+1908426 for B
2MASS J16214783+1909214 for C
2MASS J16215134+1910409 for the mystery star

Couldn't get past that so I'll have to explore another avenue.
