   They are very bright 2MASS sources.

   HM Sge:

2MASS 194157.072 +164439.48 (2000.0)  0.000  0.000  0.000
2MASS 194157.072 +164439.84 (2000.0)  0.000  0.000  0.000
2MASS 194157.086 +164439.85 (2000.0)  7.619  6.011  4.652

   V1016 Cyg:

2MASS 195705.030 +394936.33 (2000.0)  7.017  5.794  4.721
2MASS 195705.064 +394935.76 (2000.0)  0.000  0.000  0.000
